35. Search Insert Position

Posted 2020-12-16 whatyouthink

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.

给一个数组nums和一个数字target，求target出现的位置，如果没出现，求应该插入的位置。

二分就可以啦

class Solution(object):
    def searchInsert(self, nums, target):
        """
        :type nums: List[int]
        :type target: int
        :rtype: int
        """
        l = 0
        r = len(nums) - 1
        while l <= r:
            mid = (l + r) // 2
            if nums[mid] == target:
                return mid
            elif nums[mid] > target:
                r = mid - 1
            else:
                l = mid + 1
        return l
