GREEDY ALGORITHMS The **proof** of the correctness of a greedy algorithm is based on three main steps: 1: The algorithm terminates, i.e. the while loop performs a ﬁnite number of iterations. 2: The partial solution produced at every iteration of the algorithm is a subset of an optimal solution, i.e. for each.<b>Greedy</b> is an algorithmic paradigm that builds up a solution piece.

What you have then is a polynomial whose first term is divisible by 240. You now need to prove that the rest of it is also div by 240. The rest is \(\displaystyle 10(k^4+4k^3+8k^2+8k+3)\). I factorised out the 10 to keep the numbers smaller. So you need to show that the bracketed expression is div by 24.
