Java program to reverse a string using stacks - In this article, we will understand how to reverse a string using stacks. String is a datatype that contains one or more characters and is enclosed in double quotes(“”). The stack is a linear data struct

public class Main { // Method to reverse each word in a given string. public void reverseEachWordInString(String str1) { // Split the input string into individual words. String[] each_words = str1.split(" "); String revString = ""; // Iterate through each word in the array. for...
using System; namespace CS01 { class Program { public static void swap(ref int x, ref int y) { int temp = x; x = y; y = temp; } public static void Main (string[] args) { int a = 5, b = 10; swap (ref a, ref b); // a = 10, b = 5; Console.WriteLine ("a = ...
Reverse Sentence Without Words Write a Java program to reverse a sentence (assume a single space between two words) without reverse every word.

String palindrome = "Dot saw I was Tod"; int len = palindrome.length(); Apalindromeis a word or sentence that is symmetric—it is spelled the same forward and backward, ignoring case and punctuation. Here is a short and inefficient program to reverse a palindrome string. It invokes theStr...

“The name of the field XYZ is not the same as in the documentation ZZZ. Change ZZZ in the documentation to XYZ”. It is a foolish and outrageous error message. I immediately know that the program architecture is messed up when I see such an error message. If the test can tell me wh...

public static void main(String[] args) { Integer f1 = 100, f2 = 100, f3 = 150, f4 = 150; System.out.println(f1 == f2); System.out.println(f3 == f4); } } 如果不明就里很容易认为两个输出要么都是true要么都是false。首先需要注意的是f1、f2、f3、f4四个变量都是Integer对象引用,所以...
