Add Solidity implementation for Bubble Sort Algorithm

[Akshat0125]

Description

I’d like to add a Solidity implementation for the Bubble Sort Algorithm to this repository.

The algorithm will sort an array of unsigned integers in ascending order.

Why

This algorithm is fundamental for beginners learning Solidity’s array operations, loops, and gas optimization.
It will also help new learners understand how on-chain sorting can be implemented efficiently.

Implementation Details

• Create a new file: Sorting/BubbleSort.sol
• Implement a function bubbleSort(uint[] memory arr) public pure returns (uint[] memory)
• Add test cases to verify sorting correctness.

Type

• [ ] New Algorithm
• [ ] Solidity Implementation
