Matching Alphabet

Strings

INTRODUCTION

Welcome soldiers, we need your help! The enemy army is going to attack and we have to get ready.

Get together quickly by battalions!

TASK

Your task as a colonel is to order your lieutenants with their respective battalion, for each lieutenant a letter is assigned and each battalion is formed by numbers and the letter corresponding to its lieutenant. Your duty is to assign them in such a way that you return a string like the following: "a:11a1 b:b22 c:33c".

EXAMPLES

keyAlphabet( "a b c 11a b22 c33" ) => returns "a:11a b:b22 c:c33"
keyAlphabet( "a b c 11a1 2b2 33c3 13a1 12a1" ) => returns "a:11a1,12a1,13a1 b:2b2 c:33c3"

NOTES

There may be more than one battalion for the same lieutenant.
Both lieutenants and battalions must be ordered.
Be careful with the spaces.
