Problem 1081. Test if two numbers have the same digits
Given two integers x1 and x2, return true if the numbers written with no leading zeros contain the same digits. That is, the string representation of one number is a permutation of the string representation of the other.
For example
x1 = 1234; x2 = 4321; tf = same_digits(x1,x2)
would output
tf = true
whereas
x1 = 1234; x2 = 1244; tf = same_digits(x1,x2)
would output
tf = false

May you add some testcases concerning that ~mod(63-45,9) = true, but 63 and 45 has definitely not the same digits.
