27. Remove Element Given an array and a value, remove all instances of that valuein-placeand return the new length. Do not allocate extra space for another array, you must do this bymodifying the input arrayin-placewith O(1) extra memory. The order of elements can be changed. It doesn...
Given a sorted array nums, remove the duplicates in-place such that each element appear only once and return the new length. Do not allocate extra space for another array, you must do this by modifying the input array in-place with O(1) extra memory. Example 1: Given nums = [1,1,2...
给你两个按非递减顺序排列的整数数组nums1和nums2,另有两个整数m和n,分别表示nums1和nums2中的元素数目。 请你合并nums2到nums1中,使合并后的数组同样按非递减顺序排列。 注意:最终,合并后数组不应由函数返回,而是存储在数组nums1中。为了应对这种情况,nums1的初始长度为m + n,其中前m个元素表示应合并的元...

其他思路 假设有两个指针,分别从头和从尾向中间移动,然后比较左右两个值的绝对值大小,绝对值大的将平方和添加到最左边,一直到两个指针相遇。 class Solution:def sortedSquares(self, A):answer = [0] * len(A)l, r = 0, len(A) - 1while l <= r:left, right = abs(A[l]), abs(A[r])if ...
