Description: Bug Dynamic-Programming/MaxNonAdjacentSum.js guards the empty case with: if (nums.length < 0) return 0 length is never negative, so this is dead code. For an empty array the function falls through, sets maxIncluding = nums[0] (undefined), skips the loop, and returns Math.max(0, undefined) → NaN instead of 0. maximumNonAdjacentSum([]) // NaN (should be 0) Fix Use nums.length === 0, matching the clearly-intended behavior. Added a test file (the module had none) covering the empty array, a single element, the documented examples, and an all-negative input.
