leetcode 35 - Search Insert Position

by 데브업 2019. 2. 27.

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 4:

Input: [1,3,5,6], 0
Output: 0
/**
 * @param {number[]} nums
 * @param {number} target
 * @return {number}
 */
var searchInsert = function(nums, target) {
    if(nums.indexOf(target) != -1){
        return nums.indexOf(target);
    }
    if(nums.length == 0){return 0;}
    
    var len = nums.length;
    if(nums[len-1] <= target){
        return len;
    }
    
    for(let i = 0; i < len ; i++){
        if(target < nums[i]){
            return i;
        }
    }
};
