This is the 98th Video of our Playlist "Array 1D/2D : Popular Interview Problems" by codestorywithMIK

In this video we will try to solve a very good Array Problem : Minimum Operations to Make Array Equal to Target | Minimum Number of Increments on Subarrays to Form a Target Array | Leetcode 3229 | Leetcode 1526 | Dry Runs | 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 involves the following steps:

Initialization: Set up the necessary variables: result to store the total number of operations, and prev to track the previous value of the difference between corresponding elements in target and nums.

Iterate through arrays: For each element in the arrays:

Calculate the difference (curr) between the current elements of target and nums.
Check for a sign change between curr and prev. If a sign change occurs, add the absolute value of curr to result.
If there's no sign change, but the absolute value of curr is greater than that of prev, add the absolute difference between curr and prev to result.
Update prev to the current value of curr.
Return the result: After processing all elements, return the total number of operations stored in result. This ensures the transformation from nums to target with the minimum operations.
