2、代碼實現

public class Solution {public static String s0 = "Gold Medal";public static String s1 = "Silver Medal";public static String s2 = "Bronze Medal";public String[] findRelativeRanks(int[] nums) {if (nums == null || nums.length == 0)return null;int length = nums.length;int[] nums1 = nums.clone();//冒泡for (int i = 1; i < length; ++i) {for (int j = 0; j < length - i; ++j) {if (nums1[j] <= nums1[j + 1]) {int temp = nums1[j];nums1[j] = nums1[j + 1];nums1[j + 1] = temp;}}}String[] s = new String[length];for (int i = 0; i < length; ++i) {for (int j = 0; j < length; ++j) {if (nums1[i] == nums[j]) {if (i == 0) s[j] = s0;else if (i == 1) s[j] = s1;else if (i == 2)s[j] = s2;elses[j] = String.valueOf(i + 1);}}}return s;} }
