Interview Question Search Insert Position

Last update: 12/3/2017 12:06:00 AM


The problem is to figure out what the index of the target value would be in a sorted array. If the target value is already there, then return its position. Otherwise, return the position of where it would be.

Problem #35. Search Insert Position

Description: Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order.

You may assume no duplicates in the array.

Example 1:

Input: [1,3,5,6], 5
Output: 2
Example 2:

Input: [1,3,5,6], 2
Output: 1
Example 3:

Input: [1,3,5,6], 7
Output: 4
Example 1:

Input: [1,3,5,6], 0
Output: 0

Difficulty: Easy

Solution in Java

class Solution {
    public int searchInsert(int[] nums, int target) {
		int i;
        for(i = 0; i < nums.length; i++) {
			if(!(nums[i] < target))
				return i;
		return i;

The only case to solve this problem is to determine if the target value is not higher than current one in the array during iteration.
