Answer:
102
Step-by-step explanation:
1) A distinct digit is a digit that is not equal to another number
2) For example 2 = 2
3) The smallest 3 digit number is 100, but the digits are not distinct because 0 = 0
4) The same applies to 101. These are not distinct digits because 1 = 1
5) 102 however does not have any distinct numbers. 1 ≠ 0 ≠ 2
