Can you swap 2 strings in Java?

Swapping two strings usually take a temporary third variable. One of the approach to accomplish this is to concatenate given two strings into first string. Extract string 2 using substring (0, length(string1) – (string2)) i.e. in our case it will be substring(0, (11-4)).

How do you reverse a string without third variable?

Algorithm to Reverse String Without Temporary Variable

1. Store start index in low and end index in high.
2. Here, without creating a temp variable to swap characters, we use xor(^).
3. Traverse the input string “s”.
4. Swap from first variable to end using xor.
5. Return the final output string.

How do you split a string into two equal parts?

Algorithm

1. STEP 1: START.
2. STEP 2: DEFINE str = “aaaabbbbcccc”
3. STEP 3: DEFINE len.
4. STEP 4: SET n =3.
5. STEP 5: SET temp = 0.
6. STEP 6: chars = len/n.
7. STEP 7: DEFINE String[] equalstr.
8. STEP 8: IF (len\%n!=0) then PRINT (“String can’t be divided into equal parts”) else go to STEP 9.

How can I swap two strings in C# without using third variable?

Let’s see a simple C# example to swap two numbers without using third variable.

1. using System;
2. public class SwapExample.
3. {
4. public static void Main(string[] args)
5. {
6. int a=5, b=10;
7. Console.WriteLine(“Before swap a= “+a+” b= “+b);
8. a=a*b; //a=50 (5*10)

How do you swap two variables with a third variable in Java?

Java Program

1. import java.util.*;
2. class Swap_With {
3. public static void main(String[] args) {
4. int x, y, t;// x and y are to swap.
5. Scanner sc = new Scanner(System.in);
6. System.out.println(“Enter the value of X and Y”);
7. x = sc.nextInt();
8. y = sc.nextInt();

How do you reverse a string in Java without using another string?

Using Static method

1. import java.util.Scanner;
2. public class ReverseStringExample3.
3. {
4. public static void main(String[] arg)
5. {
6. ReverseStringExample3 rev=new ReverseStringExample3();
7. Scanner sc=new Scanner(System.in);
8. System.out.print(“Enter a string : “);

How to swap two strings in Java without third variable?

The simple approach to swap two strings in Java is by using a third variable. But, we can also swap two strings without using the third variable. Here is the simple program to swap two strings using a third variable. System.out.printf (“Before Swapping s1 = \%s and s2 = \%s. “, s1, s2);

How to swap two strings in Swift?

Swapping two strings usually take a temporary third variable. One of the approach to accomplish this is to concatenate given two strings into first string. Extract string 2 using substring (0, length (string1) – (string2)) i.e. in our case it will be substring (0, (11-4)).

How to swap two strings in C++?

Define two strings that need to be swapped. Concatenate both the strings and store it in first string. Extract the string from indexes 0 to length (string1) – (string2) using substring function and store it in string 2. Extract the string from index length (string2) till end using substring function and store it in string 1.

How to swap two strings in MySQL?

Algorithm 1 Define two strings that need to be swapped. 2 Concatenate both the strings and store it in first string. 3 Extract the string from indexes 0 to length (string1) – (string2) using substring function and store it in string 2. 4 Extract the string from index length (string2) till end using substring function and store it in string 1.
