Reverse number in python using while loop
Example 1: Reverse a Number using a while loop
Output Show
4321 In this program, while loop is used to reverse a number as given in the following steps:
Example 2: Using String slicing
Output 654321 Using the string slicing concept, you can get reverse the string. We will develop a program to reverse a number in python using while loop. To reverse a number we need to extract the last digit of the number and add that number into a temporary variable with some calculation, then remove the last digit of the number. Do these processes until the number becomes zero. To remove the last digit the modulus operator (%) will be helpful for us, and to remove the last digit division operator (/) can be used. To add the last digit first we need to multiply the previous value by 10. Once you get the logic, you can write the program in any language. Example of the reverse a number:- Procedure to find reverse of a number,
We will take integer numbers while declaring the variables. Then, find the reverse of a number using the while loop and finally, the result will be displayed on the screen.
Output:- The reverse number is = 54321 Reverse a Number in Python using While LoopIn the previous program, inputs are hardcoded in the program but in this program, input will be provided by the user.
Output for the input values test-case-1:- Enter a number: 416064 Output for the input values test-case-2:- Enter a number: 164532 Python Program to Reverse a Number using While LoopWe can also take the help of a function to reverse a number in python using while loop. A function is a block of code that performs a specific task.
Output:- Enter the number: 46894 How do you reverse a number in a while loop?C Program to reverse number using while loop. #include int main() {. int num, rnum = 0, rem;. printf("Enter any number: ");. scanf("%d", &num);. while (num != 0) {. rem = num % 10;. rnum = rnum * 10 + rem;. Can we reverse a number in Python?Python makes it easy to reverse a number by using a while loop. We use a while loop with the help of both floor division and the modulus % operator.
How do you reverse a number backwards in Python?Reversing a number using reversed Method
We use the python reversed() function to reverse a number by this method. This function returns a pointer that can iterate the string/list in reverse order. We use the join() method of python to obtain the reversed number from this iterator finally.
How do you reverse a 4 digit number in Python?Python Program to reverse the digits of a number. # Program to reverse the digits of a number literally.. # Input = 1234.. # Output = 4321.. num = int(input("Enter a number: \n")). reverse = 0.. |
