Round 1: Given a string and a style array render HTML pretty much like a rich text editor. For example: 'Hello, world', [[0, 2, 'i'], [4, 9, 'b'], [7, 10, 'u']] Output: '<i>Hel</i>l<b>o, w<u>orl</u></b><u>d</u> something like that.

I used a hash map and a stack to store the indices. I pushed the style into a stack and popped off when I hit the index. I had to write the output so I took care of not having invalid HTML having the <b> and <u> mixed up. This particular use case I had to take care. The interviewer gave me some hints around the hash map but I came up with the algorithm and implemented almost through the complete hour.</u></b>
