Problem: House Robber (LeetCode Problem 198)
Issue Linked: Closes #514
Contribution:
Added C++ solutions under C++/HouseRobber.cpp.
Implemented three approaches:
1. Recursion + Memoization — O(n) time, O(n) space
2. Tabulation (Bottom-Up DP) — O(n) time, O(n) space
3. Space Optimized DP (Final Solution) — O(n) time, O(1) space
• Included clear comments and structured code for readability.
• Added example test case for validation.
Example:
Input: [2,7,9,3,1]
Output: 12
