Here is my code https://ide.codingblocks.com/s/99199
I think the problem is when mid^k becomes very large and long long int cannot store it.
What should I do?

hey @Mp18, the problem is when you use break in the inner loop, program control is going outside the while loop of testcases also.
Make a function which will be called for every testcase and return the answer.

Moreover take a ans variable and in while(start<=end), inside if condition and else if condition,add additional statement ans =mid. Return this ans to main function.
