在排序數組中查找元素的第一個和最后一個位置

class Solution {public int[] searchRange(int[] nums, int target) {int len = nums.length;int start = 0;int end = len - 1;int mid = 0;int temp = 0;while(start<=end){mid = (start+end)/2;if(nums[mid]>=target){end = mid - 1;}else{start = mid + 1;}}temp = start;end = len - 1;while(start<=end){mid = (start+end)/2;if(nums[mid]>target){end = mid - 1;}else{start = mid + 1;}}return temp>end?new int[]{-1,-1}:new int[]{temp,end};}
}
