JavaScript实现搜索插入位置算法详解

const searchInsert = (nums, target) => {
    for(let i = 0; i < nums.length; i++){
        if(nums[i] >= target) {
            return i;
        }
    }
    return nums.length;
}

const searchInsert = (nums, target) => {
    let left = 0, right = nums.length - 1;
    while(left <= right) {
        let mid = Math.floor((left + right) / 2);
        if(nums[mid] == target) {
            return mid;
        } else if(nums[mid] < target) {
            left = mid + 1;
        } else {
            right = mid - 1;
        }
    }
    return left;
}
