Hi Everyone, this is the 41st video of our Playlist "Greedy Technique : Popular Interview Problems".
Now we will be solving a good greedy based problem - Minimum Equal Sum of Two Arrays After Replacing Zeros | Crystal Clear Intuition | Leetcode 2918 | codestorywithMIK
I will explain it in full detail so that it becomes easy to understand. We will find the reason behind everything so that we understand why we did what we did.
And we will do a complete dry run

Video Summary :
The approach focuses on minimizing the total sum of two arrays by replacing each zero with the smallest possible positive integer, which is 1. It then calculates the adjusted sums of both arrays.
If one array's sum is still smaller and has no zeros left to adjust, it's impossible to make the sums equal—hence, return -1.
Otherwise, the maximum of the two adjusted sums is the minimum equal sum achievable. This ensures the most efficient use of zero replacements.
