Largest Rectangle in Histogram

**Problem Statement:** Given the required input arguments, write an efficient algorithm to solve the **Largest Rectangle in Histogram** problem. Implement the required logic as specified by standard definitions for this classic algorithmic challenge. **Hint / Expected Approach:** Monotonic increasing stack, extend left **Edge Cases to Consider:** - (1) Single bar - (2) All same height - (3) Strictly decreasing heights

Examples

Example 1
Input: [2,1,5,6,2,3]
