WebThe coin change problem would be the one where an amount is given and you're prompted to give it back in coin change (each coin can be picked more than once in a given operation). I see they work, it's just that one detail that I can't follow. It seems to me there's no reason why KP couldn't just check back against the value back on the same row. WebIn algorithmic programming, we don't "think" sir rather we rigorously prove our claim. The coin change problem can be formulated as .
