Given a string of format '2+3*2-1', calculate and return the result. No parenthesis in the input, just integers and + - * / operators. Operator precedence has to be considered. Linear time complexity and minimal data structure use is preferred.

(this is a little easier to explain if it's drawn out, but I'll try my best to do it here) Given some integer N = 2^k which represents an NxN matrix, write a function that fills the matrix with 'L' shapes, such that the entire matrix is filled except for 1 empty space. For example, a 2x2 matrix would have 3 spaces filled with one of the corners empty. And a 4x4 matrix would have the entire outer row of spaces filled, with the center 4 filled the same way the 2x2 matrix is filled.
