1. steps, ameliorate
2. approaches, better
3. modes, improve
4. measures, enhance

EXPLANATION: ‘Ameliorate’ – to make better, improve. Modes does not fit the first blank so option 3.

We_____________to inform you that we cannot include your thesis in our library, on the __________________of not receiving permission from your supervisor.

1. saddened, reason
2. lament, pretext
3. repent, justification
4. regret, grounds

EXPLANATION:

‘regret’ is a feeling of disappointment.
repent is feeling remorse for one’s own wrong doings.
lament is to mourn.
Hence the 4th option is the best fit.

To make sure the idea is understood correctly, choose the option that gives the sentence the best possible structure.

According to the passage,

1. Helen Walne is a patient of cancer.
2. Helen Walne is a megabyte megalomaniac.
3. Helen Walne thinks that constant rival surfing is the best way to improve self worth.
4. Helen Walne is a conscientious worker.

EXPLANATION: Megalomania is an obsession with doing extravagant or grand things. Helen Wayne is also obsessed with this. The other options are out of scope.

According to the passage, all of the following are not true, except

1. Helen Walne received a prize wearing a turtle neck.
2. Helen Walne’s husband feels she needs help to get out of her addiction.
3. In reality there is very little difference in the number of internet users today and five years ago.
4. Rival surfing gives a better job

EXPLANATION: Refer to 1st para line “My husband has gently…..addiction.”

It can be inferred from the passage that

1. you have gone too far when you start googling your name multiple times daily.
2. competitive rival surfing is the best way to increase your self esteem.
3. being addicted to self googling is the way forward in the 21st century.
4. the advent of the internet has helped in creating ‘a somebody’ out of ‘a nobody’.

KPIT Coding Questions and Answers For Freshers

Questions: While playing an RPG game, you were assigned to complete one of the hardest quests in this game. There are n monsters you’ll need to defeat in this quest. Each monster i is described with two integer numbers – poweri and bonusi. To defeat this monster, you’ll need at least poweri experience points. If you try fighting this monster without having enough experience points, you lose immediately. You will also gain bonusi experience points if you defeat this monster. You can defeat monsters in any order.

The quest turned out to be very hard – you try to defeat the monsters but keep losing repeatedly. Your friend told you that this quest is impossible to complete. Knowing that, you’re interested, what is the maximum possible number of monsters you can defeat?

Input:

• The first line contains an integer, n, denoting the number of monsters. The next line contains an integer, e, denoting your initial experience.
• Each line i of the n subsequent lines (where 0 ≤ i < n) contains an integer, poweri, which represents power of the corresponding monster.
• Each line i of the n subsequent lines (where 0 ≤ i < n) contains an integer, bonusi, which represents bonus for defeating the corresponding monster.

Output

• 2

Example Programs:

JAVA PROGRAM

import java.util.Arrays;
import java.util.Comparator;
import java.util.Scanner;

class Main
{
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        int n = s.nextInt();
        int exp = s.nextInt();

        int monst[] = new int[n];
        int bonus[] = new int[n];

        for (int i = 0; i < n; i++) {
            monst[i] = s.nextInt();
        }
        for (int i = 0; i < n; i++) {
            bonus[i] = s.nextInt();
        }

        class Monster {
            private final int power, bonus;
            public Monster(int power, int bonus){
                this.power = power;
                this.bonus = bonus;
            }
        }

        Monster[] monsters = new Monster[n];

        for(int i = 0; i < n; i++)
            monsters[i] = new Monster(monst[i], bonus[i]);

        Arrays.sort(monsters, Comparator.comparingInt(m -> m.power));

        int count = 0;

        for(Monster m: monsters){
            if(exp < m.power) break;
            exp += m.bonus;
            ++count;
        }
        System.out.println(count);
    }
}

Questions: One of the first lessons IT students learn is the representation of natural numbers in the binary number system (base 2) This system uses only two digits, 0 and 1. In everyday life we use for convenience the decimal system (base 10) which uses ten digits, from 0 to 9. In general, we could use any numbering system.

Computer scientists often use systems based on 8 or 16. The numbering system based on K uses K digits with a value from 0 to K-1. Suppose a natural number M is given, written in the decimal system To convert it to the corresponding writing in the system based on K, we successively divide M by K until we reach a quotient that is less than K

The representation of M in the system based on K is formed by the final quotient (as first digit) and is followed by the remainder of the previous divisionsFor example :

•  If M=122 and K=8, 122 in base 10= 172 in base 8 This means that the number
• In decimal system = 172 in octal system.
• 172 in base 8 = 1*8^2 + 7*8 + 2 = 122

You made the following observation in applying the above rule of converting natural numbers to another numbering system

•  In some cases in the new representation all the digits of the number are the same. For example 63 in base 10= 333 in base 4

Given a number M in its decimal representation, your task is find the minimum base B such that in the representation of M at base B all digits are the same.

Input Format

• The first line contains an integer, M, denoting the number given

Constraints

• 1 <= M = 10^12

Sample Input 1 :

41

Sample Output 1 :

40

Explanation :

Here 41 in base 40. will be 11 so it has all digits the same, and there is no smaller base satisfying the requirements

Sample Input 2 :

34430

Sample Output 2 :

312

Explanation :

Here 34430 in base 312 will have all digits the same and there is no smaller base satisfying the requirements

Example Programs:

JAVA PROGRAM

import java.util.*;
class Main
{
  public static boolean convertBase (int m, int base)
  {

    int rem = m % base;
      m = m / base;

    while (m >= base && (m % base == rem))
      m = m / base;

    if (m == rem)
      return true;

      return false;
  }

  public static void main (String[]args)
  {
    Scanner sc = new Scanner (System.in);
    int m = sc.nextInt ();
    int base = 2;

    while (convertBase (m, base) != true)
      base++;

    System.out.println (base);

  }

}

Q) You have been given a string S of length N. The given string is a binary string that consists of only 0’s and ‘1’s. Ugliness of a string is defined as the decimal number that this binary string represents.

 Example:

• “101” represents 5.
• “0000” represents 0.
• “01010” represents 10.

There are two types of operations that can be performed on the given string.

• Swap any two characters by paying a cost of A coins.
• Flip any character by paying a cost of B coins
• flipping a character means converting a ‘1’to a ‘0’or converting a ‘0’ to a ‘1’.

Initially, you have been given coins equal to the value defined in CASH. Your task is to minimize the ugliness of the string by performing the above mentioned operations on it. Since the answer can be very large, return the answer modulo 10^9+7.

Note:

• You can perform an operation only if you have enough number of coins to perform it.
• After every operation the number of coins get deducted by the cost for that operation.

Input Format

• The first line contains an integer, N, denoting the number of character in the string
• The next line contains a string, S, denoting the the binary string
• The next line contains an integer, CASH, denoting the total number of coins present initially
• Next will contains an integer, A, denoting the cost to swap two characters.
• Then the next line contains an integer, B, denoting the cost to flip a character.

Constraints

• 1 <= N <= 10^5
• 1< len(S)<= 10^5
• 1<=CASH <=10^5
• 1<=A<=10^5
• 1<=B<=10^5

Sample Input 1 :

4
1111
7
1
2

  Sample Output 1 :

1

  Explanation:

3 flips can be used to create “0001” which represents 1.

  Sample Input 2:

6
111011
7
1
3

  Sample Output 2:

7

  Explanation:

First swap 0 with the most significant 1, then use flip twice first on index one and then on index two “111011”=>”0111111″=>”001111″=>”000111″ the value represented is 7.

  Sample Input 3:

6
111011
7
3
2

  Sample Output 3:

3

 Explanation:

Flip the 3 most significant characters to get “000011” : the value represented by this string is 3.N
