Last remaining character after repeated removal of the first character and flipping of characters of a Binary String, Find repeated character present first in a string, Efficiently find first repeated character in a string without using any additional data structure in one traversal, Repeated Character Whose First Appearance is Leftmost, Count of substrings having the most frequent character in the string as first character, Count occurrences of a character in a repeated string, Find the character in first string that is present at minimum index in second string, Queries to find the first non-repeating character in the sub-string of a string, Check if frequency of character in one string is a factor or multiple of frequency of same character in other string. Is there any particular way to do it apart from comparing each character of the string from A-Z This is going to scan the string 26 times, so you're going to potentially do 26 times more work than some of the other answers. This ensures that all --not only disjoint-- substrings which have repetition are returned. Here is simple solution using the more_itertools library. *\1)", mystring)) This matches the longest substrings which have at least a single Pre-sortedness of the input and number of repetitions per element are important factors affecting For the above example, this array would be [0, 3, 4, 6]. Input a string from the user. Initialize a variable with a blank array. Iterate the string using for loop and using if statement checks whether the character is repeated or not. On getting a repeated character add it to the blank array. Print the array. Step 6:- Increment count variable as character is found in string. String s1 = sc.nextLine(); Thanks for contributing an answer to Stack Overflow! Let's go through this step by step. the code below. Because (by design) the substrings that we count are non-overlapping, the count method is the way to go: and if we add the code to get all substrings then, of course, we get absolutely all the substrings: It's possible to filter the results of the finding all substrings with the following steps: It cannot happen that "A_n < B_n" because A is smaller than B (is a substring) so there must be at least the same number of repetitions.
