Serializing string arrays in solidity

Too Long; Didn't Read

Solidity is still in development and that’s why it still lacks in a lot of features that a good programming language should have. One of the features which solidity is missing is that it cannot return or take multi-dimensional arrays as input. Well, that does not seem important but when we talk about strings, we realize that they are just arbitrary-length byte array(i.e. <code class="markup--code markup--p-code">byte[]</code>). So when you create a string array, you are creating a two-dimensional byte array(i.e. <code class="markup--code markup--p-code">byte[][]</code>). This is where we all get stuck. Kinda like a trap…
