DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER

DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER is a DSA topic. In plain words you use it for a short DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER example you can type. Type it, run it, and say what you see. If you can do that from memory, you know DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER.

From the example next to this theory: DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER — greedy picks the locally best choice each step (works for canonical coin systems).

Trap: only saying “DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER” with no example. Fix that before you talk about advanced DSA.

Viva: what is DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER? Then show the smallest DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER example you can type. Then name the trap.

What is DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER? Show this: the smallest DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER example you can type. Trap: only saying “DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER” with no example.

Example

def coin_change_greedy(amount, coins=(25, 10, 5, 1)):
    used = []
    for c in coins:
        while amount >= c:
            amount -= c
            used.append(c)
    return used

print(coin_change_greedy(40))

DIFFERENCE BETWEEN GREEDY AND DIVIDE AND CONQUER — greedy picks the locally best choice each step (works for canonical coin systems).
