1. 概述 在处理需要检查给定数组中某些范围的答案的问题时,滑动窗口算法可能是一种非常强大的技术。 在本教程中,我们将解释滑动窗口技术及其变体,即固定窗口大小和灵活窗口大小。此外,我们将提供两种变体的示例,以便更好地理解。 2. 理论思想 滑动窗口技术背后的主要思想是将两个嵌套循环转换为单个循环。通常,该技术...
Given an array nums, there is a sliding window of size k which is moving from the very left of the array to the very right. You can only see the k numbers in the window. Each time the sliding window moves right by one position. 这题要求找到given数组中任意定长的滑动窗口中数的最大值...
