In this video we will try to solve a good Problem : Check If Array Pairs Are Divisible by k | Simplest Explanation | Dry Run | Leetcode 1497 | codestorywithMIK
I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

Summary :
The approach uses remainder arithmetic to solve the problem of determining if the array can be rearranged into pairs whose sums are divisible by a given integer k. Here's a brief summary of the method:
Calculate Remainder Frequencies:
Traverse through the array and compute the remainders when each element is divided by k.
Use an array mp of size k to count the frequency of these remainders, handling negative remainders correctly.
Check Conditions for Valid Pairing:
For elements with a remainder of 0, their frequency must be even to ensure they can be paired.
For other remainders rem, ensure that mp[rem] (frequency of rem) matches mp[k - rem] (frequency of its complement remainder) to allow pairing.
Return Result:
If all conditions are met, return true; otherwise, return false.
