The programming constructs of sequence, selection and iteration can be combined to make more complex programs.
Analysing a problem involves decomposing it into its constituent parts.
Algorithms can be developed to solve a problem.
A problem can be solved in multiple ways.

Programming constructs cannot be combined in the same code block.
