The typical format of an assembly language source statement is:

label operation operand comment

Create an algorithm that will read in a line and split it into the label, operation, and operand fields. For this problem, assume that a label (if present) must begin in the first column and that the other fields are separated by one or more spaces (not tabs, for simplicity). Unless the line is empty, all fields should be empty.

Be explicit! Don't assume any functions available in any compiler or library. No code - just the algorithm (pseudocode).
