Acquire and Release Strategy

Pepcoding Video Explaination

The generalized approach for Acquire and Release strategy :

Certainly! Here’s a generalized description of the acquire and release strategy:

1. Initialization:

• Initialize two pointers, start and end, representing the window boundaries.
• Initialize any necessary variables to track conditions within the window.
• Initialize a result variable to store the maximum window size.

2. Main Loop (While within array bounds):

• Acquire:

  • Move the end pointer forward to expand the window.
  • Update any relevant variables based on the newly added element.

• Release (if necessary):

  • While the window is invalid or violates certain conditions:
    • Move the start pointer forward to release elements from the window.
    • Update relevant variables accordingly.

• Calculate Window Size:

  • Determine the size of the current window using the start and end pointers.
  • Window Size is : ==(end - 1) - (start + 1) - 1 or end - start - 1==.

• Update Result:

  • Update the result variable based on the current window size and the previous result.

3. Return Result:

• The final result represents the desired outcome based on the window criteria.

This general strategy can be adapted for various problems that involve maintaining a valid window or subarray while iterating through an array. The specific conditions for acquisition, release, and window size calculation will depend on the requirements of the problem at hand.
