Unthinkable Solutions Coding Questions and Answers 

Q) Problem Statement  :

You will be given a left limit and a right limit. You need to Calculate the sum of all prime numbers between a given range x and y, both inclusive.

Sample Test Case :
Input :      Output :
30             68
40

Explanation :
31 and 37 are the two prime numbers in the window.

C++ PROGRAM 

#include <bits/stdc++.h>

using namespace std;
unordered_map < int, bool > prime;
void SieveOfEratosthenes(int n) {
    for (int i = 0; i < n; i++) prime[i] = 1;
    for (int p = 2; p * p <= n; p++)
        if (prime[p] == true)
            for (int i = p * p; i <= n; i += p) prime[i] = false;
}
int main() {
    int n, m;
    int count = 0, sum = 0;
    cin >> n >> m;
    SieveOfEratosthenes(m + 1);
    for (int i = n; i <= m; i++)
        if (prime[i]) sum += i;
    cout << sum;
}

JAVA PROGRAM 

import java.util.*;
public class Main {
    public static boolean isPrime(int no) {
        if (no <= 1)
            return false;
        if (no <= 3)
            return true;
        if (no % 2 == 0 || no % 3 == 0)
            return false;
        for (int i = 5; i * i <= no; i = i + 6) {
            if (no % i == 0 || no % (i + 2) == 0)
                return false;
        }
        return true;
    }
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int x = sc.nextInt();
        int y = sc.nextInt();
        int sum = 0;
        for (int i = x; i <= y; i++)
            if (isPrime(i))
                sum = sum + i;
        System.out.println(sum);
    }
}

PYTHON PROGRAM 

def isPrime(n):
    if n <= 1:
        return False
    for i in range(2, int(n**0.5) + 1):
        if n % i == 0:
            return False
    return True


a = int(input())
b = int(input())
x = 0 if a > 2 else 2
step = 1 if (a % 2 == 0) else 0
for i in range(a + step, b + 1, 2):
    if isPrime(i):
        x = x + i
print(x)

Q) Problem Statement  :

There are two major scales for measuring temperature, celsius & Fahrenheit.Given a floating point input for temperature in celsius scale, Write a program to convert celsius to fahrenheit, up till 2 decimal points.

Input     Output
56           132.8

Explanation:
56 degrees celsius means132.8 degrees of Fahrenheit to be exact.

C++ PROGRAM 

#include 

using namespace std;

int main() {
  float temperature;
  cin >> temperature;
  cout << (temperature * 9) / 5 + 32;
  return 0;
}

JAVA PROGRAM 

import java.util.*;
public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        float n = sc.nextFloat();
        float ans = ((n * 9.0 f / 5.0 f) + 32.0 f);
        System.out.println(ans);
    }
}

PYTHON PROGRAM 

def ctof(c):
    return (c * 9) / 5 + 32
temperature = float(input())
ans = ctof(temperature)
print(round(ans, 2))

Q) Problem Statement  :
You are given an array, You have to choose a contiguous subarray of length ‘k’, and find the minimum of that segment, return the maximum of those minimums.
Sample input :
1 → Length of segment x =1
5 → size of space n = 5
1 → space = [ 1,2,3,1,2] 2
3
1
2

Sample output :
3
Explanation :
The subarrays of size x = 1 are [1],[2],[3],[1], and [2],Because each subarray only contains 1 element, each value is minimal with respect to the subarray it is in. The maximum of these values is 3. Therefore, the answer is 3

C++ PROGRAM

    if(arr[start-1]==prevmin) return prevmin;
    return prevmin=(arr[end] <= prevmin)?prevmin:sorting(start,end);

     min=Math.min(min,arr[j]);
   max=Math.max(min,max);     
 }
 System.out.println(max);
}
}

for i in range(n):
    arr.append(int(input()))
s,a=0,0

Q) Problem Statement  :
There are some groups of devils and they splitted into people to kill them. Devils make People to them left as their group and at last the group with maximum length will be killed. Two types of devils are there namely “@” and “$”
People is represented as a string “P”

Input Format:
First line with the string for input

Output Format:
Number of groups that can be formed.

Constraints:
2<=Length of string<=10^9

Input string
PPPPPP@PPP@PP$PP

Output
7

Explanation
4 groups can be formed
PPPPPP@
PPP@
PP$
PP

Most people in the group lie in group 1 with 7 members.
