lists in vector

[srilu]

Hi, I have a requirement like this.
I need to have an array of pointers to linked lists.
If for ex, I give some number as input to the function, it should check for the that value in the array and if present, it should add "x" value to the list pointing to that element.
if no element is present in the list, it should create a new list and add the input to the list.

I m new to development, and any help in this regard, would be appreciated.

thanks
