Mirror Distance of an Integer
Easy
You receive an integer n.
Define its mirror distance as: abs(n - reverse(n)) where reverse(n) is the integer formed by reversing the digits of n.
Find and provide an integer denoting the mirror distance of n.
abs(x) denotes the absolute value of x.
Example 1
Input: n = 25
Output: 27
Explanation:
-
reverse(25) = 52. -
Thus, the answer is
abs(25 - 52) = 27.
Example 2
Input: n = 10
Output: 9
Explanation:
-
reverse(10) = 01which is 1. -
Thus, the answer is
abs(10 - 1) = 9.
Example 3
Input: n = 7
Output: 0
Explanation:
-
reverse(7) = 7. -
Thus, the answer is
abs(7 - 7) = 0.
Constraints
