Find Matching pairs of numbers

How could code be written to output a number for every two numbers that are identical? For example given 223323436577 would print out 2 3 7.

You have not mentioned the language but in python its very simple, l=set(map(int,list(input()))) for i in l: print(i,end=' ') Here we have split the input and the set converts all the same type of digits into a single value or in short deletes all duplicate values from the input.

The best way, in my opinion, would be to convert whatever it is into a String, then run it through a Regular Expression Comparison. Find recurring numbers, assign them to an array then print the result. For a step-interval of 2 if looping through, use your language's equivalent of the 'continue' statement to repeat without execution.
