这里我们只要找到与x最接近的数,然后在这个数两边找k个即可。 代码如下:python:class Solution: def findClosestElements(self, arr: List[int], k: int, x: int) -> List[int]: ind = self.findColestIndex(arr,x) lo = hi = ind res = [arr[ind]] for i in range(k-1): if lo-1<0: ...
Given asortedinteger arrayarr, two integerskandx, return thekclosest integers toxin the array. The result should also be sorted in ascending order. An integerais closer toxthan an integerbif: |a - x| < |b - x|, or |a - x| == |b - x|anda < b Example 1: Input:arr = [1,2...
Given a sorted array, two integers k and x, find the k closest elements to x in the array. The result should also be sorted in ascending order. If there is a tie, the smaller elements are always preferred. Example 1: Input: [1,2,3,4,5], k=4, x=3 Output: [1,2,3,4] Exam...
