The current implementation of the
canPairfunction uses an unordered set to track remainders. However, this approach has a significant flaw: sets store only unique values and do not account for multiple occurrences of the same remainder. This leads to incorrect results in certain cases.Example
Consider the following example:
k = 6nums = [10, 4, 2, 2]Issue
In the example above, the remainders are:
10 % 6 = 4
4 % 6 = 4
2 % 6 = 2
2 % 6 = 2
The set will store only unique values, so it will not correctly handle the multiple occurrences of the remainder . This results in an incorrect outcome.
