This is the 58th Video of our Playlist "Leetcode Easy : Popular Interview Problems" by codestorywithMIK
In this video we will try to solve an easy but good practice sliding window based Problem : Defuse the Bomb | Detailed for Beginners | Leetcode 1652 | 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 above solves the problem by using a sliding window technique to calculate the sum of a specified number of elements (k) around each index in a circular array. Here's a summary:
Handle Special Case: If k is 0, the result is a vector of zeros, as no decryption is needed.
Define Initial Window:
When k greater than 0, the initial window starts from index 1 to k.
When k less than 0, the window starts near the end of the array, accounting for the negative shift.
Calculate Initial Window Sum:
The windowSum is initialized as the sum of elements in the specified window (i to j).
Sliding Window Logic:
Traverse the array using a sliding window approach.
For each position, update the windowSum by subtracting the element that goes out of the window (i) and adding the element that enters the window (j + 1).
Adjust indices i and j in a circular manner using modulo operations.
Store Results:
Store the windowSum for each index in the result vector.
