这是一个Java程序,用于解决LeetCode题目中的“Find the Missing Number”问题。该程序的主要功能是在一个给定的整数数组中找出缺失的数字。 具体实现过程如下: 1. 首先,创建一个名为`findMissingNumber`的方法,该方法接收一个整数数组作为参数。 2. 然后,遍历数组中的每个元素,将其与数组长度减一的结果进行比较。
Given a sorted array of n distinct integers where each integer is in the range from 0 to m - 1 and m > n. Find the smallest number that is missing from the array. Analysis: Solution 1. O(n), linear scan; Solution 2. O(log n), binary search: if arr[mid] > mid, then the f...

Btw, If you don't know how to sort a Map on values, see this tutorial first. It will teach youhow to sort HashMap on values in Java. Now getting key and value sorted should be easy, but rememberHashMapdoesn't maintain order, so you need to use a List to keep the entry in sort...
