Goal: Learn to concatenate lists.

Assignment: Assume two lists list$1$ and list$2,$ already declared and filled. Write a snippet of code that interleaves the two lists, and assigns the result to a list interleaved.

For example:

list$1=[1,2,3]$

list$2=[\text{'}$a$\text{'},\text{'}$b$\text{'},\text{'}$c$\text{'}]$

interleaved$=[1,\text{'}$a$\text{'},2,\text{'}$b$\text{'},3,\text{'}$c$\text{'}]$

Note: Your code should take into account cases where the two lists are of different lengths. In that case, the interleaving will be executed as usual, and any remaining elements of the longer list will be appended to the end of interleaved.
