Follow the steps given below: Read a number (num) from the user. Find the square of the given number and store it in a variable (square). Find the last digit (s) of the square. Compare the last digit (s) of the variable with num. If they are not equal, the given number is not an automorphic number. If they are the same, go to the next step.
Sep 14, 2023 · Given a number N, the task is to check whether the number is an Automorphic number or not. A number is called an Automorphic number if and only if its square ends in the same digits as the number itself. Examples : Input : N = 76. Output : Automorphic. Explanation: As 76*76 = 57 76. Input : N = 25. Output : Automorphic.
Jan 11, 2024 · Here’s one way to determine if a number is automorphic: The above approach loops through the digits of the input number in a reverse way. Let’s write a Java program to implement this approach. The isAutomorphicUsingLoop () method takes an integer as input and checks if it’s automorphic: int square = number * number; while (number > 0 ...
Jul 5, 2020 · Steps to Check Automorphic Number in Java. Input a number (num). Square the number (sqr). Count the number of digits of (num) using while loop (c). Compare the last (c) digits of (sqr) with the (num). If they are equal then the number is Automorphic else not.
Jun 17, 2022 · Here we are writing a java program to check if a given number is automorphic. To do this, we have created a user-defined method checkAutomorphic(), this method takes the number as an input and then returns true if number is an automorphic number else it returns false. The steps followed in checkAutomorphic () are: Find the square of input number.
Jul 22, 2024 · 376^2 = 141,376. Step 2: Check if the square ends with the original number. The square (141,376) ends with 376, which is the original number. Therefore, 376 is an automorphic number. Let’s put this process into a step-by-step algorithm: 1. Take a number as input. 2. Calculate the square of the number.
Oct 18, 2021 · We can also use String’s endsWith () method to find automorphic number using String. Here is simple algorithm to find automorphic number using digits. Take value of n from user using Scanner class and convert it to String numStr. Find square of n and convert it to String sqrNumStr. Check if sqrNumStr with numStr.
