LeetCode——Search for a Range

Description：

Given a sorted array of integers, find the starting and ending position of a given target value.

Your algorithm's runtime complexity must be in the order of O(log n).

If the target is not found in the array, return [-1, -1].

For example, Given [5, 7, 7, 8, 8, 10] and target value 8, return [3, 4].

 

public class Solution {
    public int[] searchRange(int[] nums, int target) {
        int flag = -1, start=-1, end = -1;
        for(int i=0; i<nums.length; i++) {
            if(nums[i] == target) {
                start = i;
                for(int j=i; j<nums.length; j++) {
                    if(nums[j] != target) {
                        end = j-1;
                        flag = 1;
                        break;
                    }
                    if(nums[j]==target && j==nums.length-1) {
                        end = j;
                        flag = 1;
                        break;
                    }
                }
            }
            if(flag == 1) {
                break;
            }
            
        }
        
        return new int[]{start, end};
    }
}
