HackerRank — A Very Big Sum | Python 3 | Easy Array Warmup Challenge

Today I solved the HackerRank problem: “A Very Big Sum” 🔢 This challenge was very straightforward: read the array iterate through each number accumulate the total sum return the result What made this session interesting wasn’t the difficulty itself, but the psychological context around it. After struggling previously on a LeetCode optimization problem, I noticed I had developed a bit of apprehension toward harder algorithmic exercises. So I intentionally started with HackerRank to rebuild momentum and confidence before returning to more difficult problems.
