Adding Kadane's algothirm to array in data_structures folder

[Siddhart2004]

Feature description

📋** Topic**: Kadane's algothirm

Description

Kadane’s algorithm is a popular algorithm used to find the maximum sum of a contiguous subarray in an array with a time complexity of O(n). It efficiently handles both positive and negative numbers, making it an essential part of algorithmic problem-solving.
This algorithm can be a valuable addition to the project’s library under the "array" section, improving resources for learners and contributors.

I would like to work on this.
