A Number After a Double Reversal
Reversing an integer means to reverse all its digits.
- For example, reversing
2021gives1202. Reversing12300gives321as the leading zeros are not retained.
Given an integer num, reverse num to get reversed1, then reverse reversed1 to get reversed2. Return true if reversed2 equals num. Otherwise return false.
Example 1
Input
num = 526Output
trueReverse num to get 625, then reverse 625 to get 526, which equals num.
Example 2
Input
num = 1800Output
falseReverse num to get 81, then reverse 81 to get 18, which does not equal num.
Constraints
- 0 <= num <= 10^6
