In this video, we solve Leetcode Problem 2434 - Robot With String using a stack-based greedy approach. You'd like to concatenate them together in some order such that the resulting string would be lexicographically smallest. For example, s = "axxb??" the two question marks can be replaced with the characters a and b respectively to form a string s ="a Link - Complete the function SmallestAndLargestSubstring, which takes a string S consisting of lowercase English letters (a-z) as its argument and returns lexicographically smallest and largest … Given a string, I need to find the longest palindrome that can be constructed by removing or shuffling characters from the string. For example, if the input string is “ABC”, then output should be “ABC, ACB, BAC, BCA, CAB, CBA”. Intuitions, example walk through, and complexity … Note that a string x is lexicographically smaller than string y if x comes before y in dictionary order, that is, either x is a prefix of y, or if i is the first position such that x[i] != y[i], then x[i] comes before y[i] in alphabetic order. You are allowed to replace at most one character in the string with an arbitrary lowercase Latin letter. Apply one of the following … The smallest lexicographical order is an order relation where string s is smaller than t, given the first character of s (s1) is smaller than the first character of t (t1), or in case they are … Lexicographically smallest palindrome with minimal changes Strings of length N with no palindromic sub string Check if any anagram of a string is palindrome or not Count maximum-length palindromes Next greater palindromic … Basically lets say at each index of the string you know which alphabets could be in that index, and then you want to find lexicographically smallest arrangement. 3K subscribers Subscribe Given a string S of N characters, the task is to find the smallest lexicographical string after performing each of the following operations N times in any order: Remove the 1st character of S and insert it into a stack X.
