This problem is from Five programming problems every Software Engineer should be able to solve in less than 1 hour which itself is an interesting read. The first few problems are trivial, but the fourth one can be a bit more interesting.

Given a list of integers separated by a single space on standard input, print out the largest and smallest values that can be obtained by concatenating the integers together on their own line.

For example:

Input:

5 56 50

Output:

50556
56550

Various points of order:

  • The order of the results are smallest then largest.
  • Only the smallest and largest values may be printed out (iterating over all the variations and printing them out isn't valid).
  • There will always be two or more integers in the list.
  • It is possible for the largest and smallest results to be the same. In the case of input 5 55, the number 555 should be printed twice.
  • The integers are not necessarily distinct. 5 5 is valid input.
  • Leading 0s on integers are not valid input. You will not need to account for 05 55.

As this is code golf, shortest entry wins.
