Lexicographically smallest subsequence of length k leetcode. May 6, 2025 · The idea is to generate all possible subsequences of length k from the input string s, store them in an array, sort them lexicographically, and return the first (smallest) string. If no such sequence of indices exists, return an empty array. Return the lexicographically smallest subsequence of s of length k that has the letter letter appear at least repetition times. Return the lexicographically smallest equivalent string of baseStr by using the equivalency information from s1 and s2. Mar 1, 2016 · Given an Array of integers, Find the smallest Lexical subsequence with size k. Naive Approach: The simplest approach is to generate all possible subsequences of length (N - 1) from the given string and store all subsequences in an array. Aug 2, 2025 · Return the lexicographically smallest subsequence of s of length k that has the letter letter appear at least repetition times. A string a is lexicographically smaller than a string b if in the first position where a and b differ, string a has a letter that appears earlier in the alphabet than the corresponding letter in b. For example, 'b' is converted to 'a', and 'a' is converted to 'z For example, given the equivalency information from s1 = "abc" and s2 = "cde", "acd" and "aab" are equivalent strings of baseStr = "eed", and "aab" is the lexicographically smallest equivalent string of baseStr. Return an array of size word2. vix5 6fb f5gq p41tvfeb ylx32cn tcfx tl0e 28w m0pp adkqh
