In this video, we solve 𝐂𝐨𝐝𝐞𝐟𝐨𝐫𝐜𝐞𝐬 𝐏𝐫𝐨𝐛𝐥𝐞𝐦 𝐀 - 𝐃𝐢𝐝 𝐖𝐞 𝐆𝐞𝐭 𝐄𝐯𝐞𝐫𝐲𝐭𝐡𝐢𝐧𝐠 𝐂𝐨𝐯𝐞𝐫𝐞𝐝? (𝟏𝟓𝟎𝟎 𝐫𝐚𝐭𝐞𝐝) using a greedy algorithm approach.⁣
⁣
This problem asks us to determine if all possible strings of length n, formed from the first k alphabets, appear as subsequences in the given string. If not, we must construct a missing subsequence.⁣
⁣
I’ll walk you through:⁣
✅ Problem breakdown⁣
✅ Key greedy observations⁣
✅ Step-by-step solution explanation⁣
✅ Optimized C++ implementation⁣
