So recently I\'ve been going through some of the problems here on LeetCode, however, I realized that they use a weird format. Here\'s one example of the expected output:\n\n```\nGiven nums = [2, 7, 11, 15], target = 9,\n\nBecause nums[0] + nums[1] = 2 + 7 = 9,\nreturn [0, 1].\n```\n\nNotice how the problem wants two values of an array returned. However, I have no clue how to do that...\n\nAny advice?
