WebLeetCode works pretty well for me. Filter by "dynamic programming" tag (or "greedy" tag, they also have that one). Try problems without looking at solution first. When you get stuck, after googling, trying things, etc. then look at Solution tab. Then code the solutions without copy/pasting. Take your time. WebA greedy algorithm constructs a solution to the problem by always making a choice that looks the best at the moment. A greedy algorithm never takes back its choices, but directly constructs the final solution. For this reason, greedy algorithms are usually very efficient. Greedy does not refer to a single algorithm, but rather a way of thinking ... high st hunters hill https://theyocumfamily.com

WebOct 1, 2024 · The algorithm is as follows: At each step, sort {a, b, c}. Append the largest valid character (if there're more than one choice, pick any of them) to the answer. "Valid" means appending the character won't form three repeating characters. Update remaining {a, b, c}. Repeat step 1-3 until there's no valid character that can be appended.
