本人只會python，學算法遇阻。發現市面上幾乎都是C，C++，JAVA的算法。求大俠指教，這幾段代碼是什么語言。其實把慕課網的相關視頻都看一些差不多也知道了，想節省時間，就只有請教各位了。謝謝?。?！public int[] twoSum(int[] nums, int target) {??? for (int i = 0; i < nums.length; i++) {??????? for (int j = i + 1; j < nums.length; j++) {??????????? if (nums[j] == target - nums[i]) {??????????????? return new int[] { i, j };??????????? }??????? }??? }??? throw new IllegalArgumentException("No two sum solution");}public int[] twoSum(int[] nums, int target) {???
