We now look to compute our overhead function, so we can use the Master Theorem. How much work is done to divide the matrix, and how much work is done to recombine? (You may want to consider the operations used to do so).

Give your answer in the form "O(f)", where f is your function inputted with no spaces. Use the caret "^" for exponentiation, and n as the function variable. For example, if you thought the solution was , you would input O(n^42).
