How do you swap values of two variables without using the third variable?

How do you swap values of two variables without using the third variable?

Program to swap two numbers without using the third variable

1. STEP 1: START.
2. STEP 2: ENTER x, y.
3. STEP 3: PRINT x, y.
4. STEP 4: x = x + y.

Can we swap 2 variables without a third one?

Given two variables, x, and y, swap two variables without using a third variable. The idea is to get a sum in one of the two given numbers. The numbers can then be swapped using the sum and subtraction from the sum.

How can I swap two strings without using third variable?

How do you swap two string variables without using third or temp variable in java?

1. public class SwapWithoutTemp {
2. public static void main(String args[]) {
3. String a = “Love”;
4. String b = “You”;
5. System.out.println(“Before swap: ” + a + ” ” + b);
6. a = a + b;
7. b = a.substring(0, a.length() – b.length());

Can we swap values of two variables without using the temporary third variable?

Swap Two Numbers Using Bitwise XOR XOR operator works in the similar manner as swapping without using temporary variable works. We extract calculate the XOR of both the variables. Then we extract individual values and swap them.

How can we swap two numbers without third variable and without arithmetic operator?

1 Answer

1. private static void swap() {
2. int a = 5;
3. int b = 6;
4. System.out.println(“Before Swaping: a = ” + a + ” and b= ” + b);
5. // swapping value of two numbers without using temp variable and XOR bitwise operator.
6. a = a ^ b; // now a is 3 and b is 6.
7. b = a ^ b; // now a is 3 but b is 5 (original value of a)

How can I swap two variables without using 3rd C++?

C++ Program to swap two numbers without third variable

1. #include
2. using namespace std;
3. int main()
4. {
5. int a=5, b=10;
6. cout<<“Before swap a= “<
7. a=a+b;//a=30 (10+20)
8. b=a-b;//b=10 (30-20)
9. a=a-b;//a=20 (30-10)

How do you swap two numbers in a string?

Algorithm

1. STEP 1: START.
2. STEP 2: DEFINE Strings str1 = “Good “, str2 = “morning ” to swap.
3. STEP 3: PRINT “Strings before swapping ” str1, str2.
4. STEP 4: str1 =str1 + str2.
5. STEP 5: EXTRACT str1 from indexes 0 to length (str1) – (str2) using substring function and store it in str2.

How can we swap two numbers without using third variable and arithmetic operator?

Which bit manipulation property is used to swap two numbers without using any third variable?

Bitwise operators can also be used to swap two numbers without using a third variable. XOR bitwise operator returns zero if both operands are the same i.e. either 0 or 1 and return 1 if both operands are different e.g. one operand is zero and the other is one.

How does XOR swap work?

In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required.

How can you swap two numbers without using a temporary variable and operators?

How to Swap two numbers without using temporary variable?

1. Swapping Using Addition and Subtraction operation. x = x + y y = x – y x = x – y.
2. Swapping Using Multiplication and Division operation. x = x * y y = x / y x = x / y.
3. Swapping Two Numbers Using XOR operation. x = x ^ y y = x ^ y x = x ^ y.

How do you swap in C programming?

What is swapping in C programming?

In C Programming swapping means replacing values of a variable with other variables. Generally, a variable can store an integer value or a float value or even a string. But swapping without the third variable is used mostly in float and numbers. What are the practical applications of Swapping in Programming?
