How many 2 digit numbers with distinct digits are there?
2-digit integers: 10, …, 99 – there are 90 integers, but in 9 of them (11, …, 99) the two digits are the same. So there are 90 − 9 = 81 2-digit integers with distinct digits.
How do you check if all the digits of a number are distinct?
Another Approach: Use set STL for C++ and Java Collections for Java in order to check if a number has only unique digits. Then we can compare the size of string s formed from a given number and newly created set. For example, let us consider the number 1987, then we can convert the number into the string, C++
