Doubt in XOR profit

#1

The code is running fine, but the two test cases are not being passed.
Here is the link of the code given below.

#2

Hello @ratulhans,

There are two mistakes in your code:

  1. You are iterating both the loops from 1 to a and 1 to b resp., which is wrong.
    It is mentioned in the question: x <= a <= b <= y.
    Solution:
    Both loops will iterate from x to y (i.e. a and b in your program)
    This is because you have to find XOR of the number lying between and on x and y.

  2. For each iteration of loop, you are checking for the XOR of a and b, which is giving right answer for the given sample testcases.
    But, the logic is incorrect.
    Solution:
    check for i^y

I have modified your mistakes, you can check it here:

Hope, this would help.
Give a like, if you are satisfied.
