Kata Day 13: Unique in Order

It was a simple Kata. What we are given is a string which contain a number of characters which can be repeated. We have to find the unique characters in the given order. So I created an answer array and looped through every character of the sequence. I checked if the character at the current index is equal to the character at the very next index or not. If it was not equal then I pushed the character at current index to the answer array.

When we have iterated through the entire array, we output the answer array.
