Lexicographically smallest string hackerrank. I am first taking smallest = the first substring of the required length i. length ()-k position to find the different possible substrings of length k , and comparing them with my current smallest and largest substrings , using compareTo () function which has int returntype . ,z). Input Format The first line contains a string denoting . Select and change only the first character. Your task is simple, given a string, find out the lexicographically smallest and largest substring of length k. Can you find the length of the lexicographically smallest string such that it has exactly sub-strings, each of which are palindromes? Lexicographical order is often known as alphabetical order when dealing with strings. Given a string, , and an integer, , complete the function so that it finds the lexicographically smallest and largest substrings of length . Determine how many strings within an array range are lexicographically smaller than or equal to the string S. For example, the substrings of abc are a, b, c, ab, bc, and abc. k.
