This is the 41st Video of our Playlist "Array (2-D & 1-D) Popular Interview Qns"
In this video we will try to solve an easy but good practice 2-D array problem - Difference Between Ones and Zeros in Row and Column (Leetcode - 2482).
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.

Approach Summary :
The approach involves iterating through the elements of the input grid to count the number of ones in each row (rowOnes) and each column (colOnes). Then, another set of nested loops calculates the difference between the count of ones in the current row/column and the count of zeros in the corresponding row/column for each element, storing the results in a new 2D vector named diff. Finally, the computed differences are returned as the output. In summary, the method aims to provide a matrix (diff) where each element represents the difference between the count of ones in the corresponding row and column and the count of zeros in those respective rows and columns of the input grid.
