I am interested to work on this issue @nilshah98 , but before assigning can you please explain what I need to resolve for solving this issue ,thanks.

Check the code for Catalan Number, it uses nCr, but it is actually written as a whole. The task here is to reduce the redundancy and use the nCr function, instead of actually writing the whole function.

You need to make changes to the existing catalan number file, and not make a new one. src\catalan\index.js make changes to this.

Oh, sorry I took it in a different way , I will come up with a new PR .
