public class TwoSum { public static int[] findTwoSum(int[] list, int sum) { for (int i = 0; i < list.length; i++) { for (int j = i + 1; j < list.length; j++) { if (list[i] + list[j] == sum) { return new int[] { i, j }; } } } return null; } } Use code with caution. The "Two Sum" Algorithm Common tasks include converting

: While the nested loop (O(n²)) works for simple tests, using a HashMap can optimize this to O(n) complexity, which may be required for performance-based questions. 2. String Manipulation and Formatting
