Can you please tell what is the problem in my code?

@Ak07
Can you plz explain me your logic? Where are you checking whether your sum is equals to target or not. you aren’t even using target variable in the function.

#3

also in the question we it is already given that target=0 so we dont have to input from the user

#4

using the sum i am trying to calcluate the sum of that particular subset

#5

Check line 11, 12 and 13. here first you are initializing b[j] with a[i], then makes sum=0 and then initialize sum with b[j]. This means that your sum=a[i], which is equals to zero only if a[i] is 0. I don’t think you are taking sum of subset. please check your code.
pass sum variable in function parameter. think this way

#7

i did as you said and it is giving the correct answers when i tried by giving custom input but it is not passing the testcases

#8

At the beginning of while loop, write count=0;
you have to initialize count with 0 for each testcase

thanks a lot, got it
