// Java program to reverse a given number // using the recursion import java.util.*; public class Main { public static int reverseNumber(int num, int len) { if (len != 1) return (((num % 10) * (int) Math.pow(10, len - 1)) + reverseNumber(num / 10, --len)); return ...
In this tutorial, you will learnhow to reverse a number in Java. For example if a given input number is19then the output of the program should be91. There are several ways to reverse a number in Java. We will mainly discuss following three techniques to reverse a number. Table of conte...

java中reverse的使用案例 java中reverse的使⽤案例reverse()⽅法表⽰的是将⼀个输⼊流倒叙输出。举例：StringBuffer sb =new StringBuffer("abcd");System.out.println(sb.reverse().toString());输出结果：dcba；备注：此⽅法针对的是io流，不能针对字符串。
首先,让我们来看看如何反转一个字符串。在Java中,我们可以使用StringBuilder类来实现这个功能。以下是使用StringBuilder类的代码示例: publicclassReverseStringExample{publicstaticvoidmain(String[]args){Stringstr="Hello, World!";StringBuilderreversedStr=newStringBuilder();for(inti=str.length()-1;i>=0;i--){re...
Reverse Integer之Java实现 一、题目 Given a 32-bit signed integer, reverse digits of an integer. Example 1: Input: 123 Output: 321 Example 2: Input: -123 Output: -321 Example 3: Input: 120 Output: 21 Note: Assume we are dealing with an environment which could only store integers within...
Reverse bits of a given 32 bits unsigned integer. For example, given input 43261596 (represented in binary as 00000010100101000001111010011100), return 964176192 (represented in binary as 00111001011110000010100101000000). Follow up: If this function is called many times, how would you optimize it?

Input Input file contains multiple test cases. There is a positive integer n (n<100) in the first line, which means the number of test cases, and then n 32-bit integers follow. Output For each test case, you should output its reverse number, one case per line. ...
