Print number in ascending order which contains 1, 2 and 3 in their digits.

Given an array of numbers, the task is to print those numbers in ascending order separated by commas which have 1, 2 and 3 in their digits. If no number containing digits 1, 2, and 3 present then print -1.

Examples:

Input : numbers[] = {123, 1232, 456, 234, 32145}
Output : 123, 1232, 32145

Input : numbers[] = {9821, 627183, 12, 1234}
Output : 1234, 627183

Input : numbers[] = {12, 232, 456, 234}
Output : -1

Approach: First finding all the number in from of array which contains 1, 2 & 3 then sort the number according to 1, 2 and 3 and then print it.
