DSA - Level 1 - Inverse of a number - Solution | Java Foundation Course | Lecture 23

Question Name: Inverse of a number Question Link: https://nados.io/question/inverse-of-a-number Question Statement: 1. You are given a number following certain constraints. 2. The key constraint is if the number is 5 digits long, it'll contain all the digits from 1 to 5 without missing any and without repeating any. e.g. 23415 is a 5 digit long number containing all digits from 1 to 5 without missing and repeating any digit from 1 to 5.Take a look at few other valid numbers - 624135, 81456273 etc.Here are a few invalid numbers - 139, 7421357 etc. 3. The inverse of a number is defined as the number created by interchanging the face value and index of digits of number.e.g. for 426135 (reading from right to left, 5 is in place 1, 3 is in place 2, 1 is in place 3, 6 is in place 4, 2 is in place 5 and 4 is in place 6), the inverse will be 416253 (reading from right to left, 3 is in place 1, 5 is in place 2,2 is in place 3, 6 is in place 4, 1 is in place 5 and 4 is in place 6) More examples - inverse of 2134 is 1243 and inverse of 24153 is 24153 4. Take as input number "n", assume that the number will follow constraints. 5. Print it's inverse. -------------------------------------------------------------------------------------------------------------------------------------------------------------- Please consume this content on nados.io for a richer experience.
