Examples: Input: str = “geeksforgeeks”, K = 4 Output: eeks Explanation: The substrings with the maximum count of vowels are “geek”, “eeks” which includes 2 vowels. If no such string exists then print -1. ->if lesser elements are less than k-1, apply same algo on right side. Lexicographical order is not always an equivalent of "dictionary order", at least this definition is not complete in the realm of programming, rather, it refers to "an ordering based on multiple criteria". In one operation you can choose any position i and delete the digit d at s[i] and insert min(d+1, 9) on any position (at the beginnin Lexicographical Order Java with java tutorial, features, history, variables, object, programs, operators, oops concept, array, string, map, math, methods, examples etc. , arr[i] = arr[i] – X) and adding the minimum value to arr[j] (arr[j] = arr[j] + X) and print the lexicographically smallest array. Source: Google Written Test. – Sep 16, 2015 · The value returned does not really matter as the compareTo contract is to return negative, positive or 0 (as you already know). util. public static String getSmallestAndLargest(String s, int k) { String smallest = ""; String largest = ""; String currStr = s. There´s a part in this solution I don´t really understand. e. You are given a 0-indexed array of positive integers nums and a positive integer limit. The first line contains an integer t, the number of queries. Note: Assume that the solution always exists. Dec 21, 2022 · Find the lexicographically smallest string that can be obtained by doing this operation at most once. In one operation, you can choose any two indices i and j and swap nums[i] and nums[j] if |nums[i] - nums[j]| <= limit. Lets just say a. input: welcometojava 3 expected output Dec 22, 2022 · Given three positive integers A, B, and K, the task is to find the Kth lexicographically smallest binary string that contains exactly A number of 0s and B number of 1s. In one operation you can choose any position i and delete the digit d at s[i] and insert min(d+1, 9) on any position (at the beginning, at the end, or in between any two adjacent digits). An array a is lexicographically smaller than an array b if in the first position where a and b differ, array a has an element that is less than the corresponding element in b.
