In terms of complexity alone, O(lgN) is faster than O(1) unless N is bigger than 1e15 or so. This happens often, even when there is a significant difference in time complexity, such as O(N) and O(N^2). If you want to know where the time complexity of hashmap, especially the ...

The Big O Notation (O()O()) provides a mathematical notation to understand the complexity of an algorithm or to represent the complexity of an algorithm. So, the idea is that time taken for an algorithm or a program to run is some function of the input size (n). This function can be...

How to calculate “hard” runtime complexity? 在技术面试中,准确说出一个解法的runtime complexity(算法时间复杂度)是一个非常重要的点。考虑到对于算法时间复杂度的理解是CS领域的基础,因此这类问题,回答对了往往那不加分,但是回答错误往往是致命的,因此大家不能掉以轻心。

There are two sorted arrays nums1 and nums2 of size m and n respectively. Find the median of the two sorted arrays. The overall run time complexity should be O(log (m+n)). 解题思路:合并两个数组,创建一个Map对象,用以存放排好顺序的键值对,键为序号,值为数组值,中位数的结果分两种情况...
