Today I am gonna to go through some string related OA questions. I will keep updating this post when I get new string questions.

String is one of the most common primitive data type in most programming languages. Some very interesting questions about string manuplications or checkings come out. Without further ado, let’s get started!

Today I found an interesting OA question related to printing matrix in spiral order, and had a shot at it. Simply googling it I find another question related to checking Toeplitz Matrix. I will keep updating this post once I found more interesting questions related to matrix operations.
