CHALLENGE : INTEGERS CONCATENATE 💻⌨️🖱️

Question

Given a set of 10 random positive integers (in range 1-100), write a code to concatenate the integers in such a way that the concatenation of the numbers gives the smallest possible integer.
Show us original list of integers and smallest number.

Example:
List: 78, 52, 5, 98, 42, 21, 9, 67, 18, 6
Smallest number :
18214252566778989

Answer 1

The sorting algorithm is a bit tricky.

I hope, that my easy key is correct:
The key is either the number, if it is 2-digit, otherwise 11*number

So 31,36,3

31 -> 31
36 -> 36
3 -> 33

and the number is 31336.

with that python takes it easy and @VcC will have no prob with a oneliner (-;

Answer 13

@cool codin
your algorithm has a prob with one digit numbers
please Test 3,31,35

good is 31335
better than 31353

Answer 16

@Ferhat it works perfectly if you only have two-digit numbers.

has a problem if threre are one-digits.

Answer 20

Here is my try in java , it can give the smallest no. which can be formed for any set of positive no.s and any range.
It was a tough one 😅 and little bit tricky.
To input 10 no.s just input 10 , then your 10 no.s , it will give the smallest no. which can be formed.
