Which algorithm is used to reverse a given number?

Algorithm to reverse number: Get the last digit of the given number by performing the modulo division (\%) and store the value in last_digit variable, likey last_digit= number \% 10. Multiply reversed by 10 and add last_digit, like reversed = reversed*10 + last_digit. Divide numbered by 10, like numbered/10.

How do you reverse a number in a for loop?

Reverse a number using for loop

1. public class ReverseNumberExample2.
2. {
3. public static void main(String[] args)
4. {
5. int number = 123456, reverse = 0;
6. //we have not mentioned the initialization part of the for loop.
7. for( ;number != 0; number=number/10)
8. {

What is reverse number in C?

Reversing number in C means printing the given number back to the front. For example, the given number is 123, then the reverse of this number is 321. Let us see how we can build this logic in the C program.

How do you reverse a set of numbers in C?

Let’s see a simple c example to reverse a given number.

1. #include
2. int main()
3. {
4. int n, reverse=0, rem;
5. printf(“Enter a number: “);
6. scanf(“\%d”, &n);
7. while(n!=0)
8. {

How do you reverse a negative number in C?

C Program to reverse a negative number using recursion:

1. int reversDigits(int num)
2. if(num > 0)
3. reversDigits(num/10);
4. rev_num += (num\%10)*base_pos;
5. int main()
6. printf(“Enter any number = “);
7. scanf(“\%d”, &number);
8. tmp = (number < 0)?(- 1 * number): number;

How do you reverse a number in C#?

C# Program to reverse number

1. using System;
2. public class ReverseExample.
3. {
4. public static void Main(string[] args)
5. {
6. int n, reverse=0, rem;
7. Console.Write(“Enter a number: “);
8. n= int.Parse(Console.ReadLine());

How do you reverse a loop in C?

C code to reverse a number using for loop

1. Declare and initialize three variables as follows int num,rem,reversed_Num=0;
2. The user is asked to enter a number and it is stored in the integer variable of ‘num’
3. The for loop is used to find the reversed number of the given number.

What do you mean by reverse of a number?

Reverse the digits to make another 2-digit number. Add the two numbers together.

How do you reverse and add a number until you get a palindrome in C?

C Program to Reverse a Number & Check if it is a Palindrome

1. Take the number which you have to reverse as the input.
2. Obtain its quotient and remainder.
3. Multiply the separate variable with 10 and add the obtained remainder to it.
4. Do step 2 again for the quotient and step 3 for the remainder obtained in step 4.

How to reverse a number in C programming with example?

From the above reverse a number in c example, User Entered value: Number = 1456 and Reverse = 0 Here, For the next iteration, Number = 0. So, the C Programming while loop condition will fail This reverse a number program allows the user to enter any positive integer.

How to reverse the digits of an integer in JavaScript?

Write a program to reverse the digits of an integer. Time Complexity: O (log (n)), where n is the input number. Time Complexity: O (log (n)) where n is the input number. We will convert the number to a string using StringBuffer after this, we will reverse that string using the reverse () method

How to get the digits of a number in C program?

We use modulus (\%) operator in program to obtain the digits of a number. To invert number look at it and write it from opposite direction or the output of code is a number obtained by writing original number from right to left.

How do you reverse a number in C with modulus?

C Program to Reverse Number This C program reverse the number entered by the user, and then prints the reversed number on the screen. For example if user enter 423 as input then 324 is printed as output. We use modulus (\%) operator in program to obtain the digits of a number.
