public static String getSmallestAndLargest(String s, int k) {. Solution: Above problem states that we have to find the smallest window that contains all the distinct characters of the given string even if the smallest string contains repeating elements. Lexicographical Order, also known as alphabetic or dictionary order, orders characters as follows: For example, ball < cat, dog < dorm, Happy < happy, Zoo < ball. Given a string, S, of length N that is indexed from 0 to N-1, print its even-indexed and odd-indexed characters as 2 space-separated strings on a single line (see the Sample below for more detail). Given a string, s, and an integer, k, complete the function so that it finds the lexicographically smallest and largest substrings of length k. The first line contains a string denoting s. The second line contains an integer denoting k . // Input Format // First line will consist a string containing english alphabets which has at most characters. Solution in java8.

Algorithm: Form a set for each string made up of its' characters; Intersect the sets; if size of intersection is > 0 YES else NO This is a valid string because frequencies are . Observe that its base and height are both equal to , … so smallest and largest should be found only among these words. HackerRank 'Simple Array Sum' Solution. Now, removing the character c leaves you with a valid string bdbd having a length of 4. Return the respective lexicographically smallest and largest substrings as a single newline-separated string. String s = "welcometojava"  has the following lexicographically-ordered substrings of length K=3: ["ava","com","elc","eto","jav","lco","met","oja","ome","toj","wel"]. 2nd line will consist an integer . Given a string s and an array roll where roll[i] represents rolling first roll[i] characters in string. We then return the first (lexicographically smallest) substring and the last (lexicographically largest) substring as two newline-separated values (i.e., ava\nwel). You must remove characters until the string is made up of any two alternating characters. We need to apply every roll[i] on string and output final string. For example, the substrings of abc are a, b, c, ab, bc, and abc. Take any two adjacent distinct characters and replace them with the third character. Note: You may find the String.split method helpful nextInt(); scan. Given a string , convert it to the longest possible string made up only of alternating characters. String has the following lexicographically-ordered substrings of length : We then return the first (lexicographically smallest) substring and the last (lexicographically largest) substring as two newline-separated values (i.e., ava\nwel). s consists of English alphabetic letters only (i.e., [a-zA-Z]). currstr=currstr.substring(1,k)+s.charAt(i); // 'smallest' must be the lexicographically smallest substring of length 'k', // 'largest' must be the lexicographically largest substring of length 'k'. Hackerrank - Super Reduced String Solution You might want to research a bit on the complexity of joining strings in java, and Hello Friends, in this tutorial we are going to learn Hackerrank Algorithm Super Reduced String. compareTo(curr) < 0) Your task is to change it into a string such that there are no matching adjacent characters. Removing either b or d at any point would not result in a valid string. For example, if string it does contain hackerrank, but does not. Given a string , determine if it is valid.If so, return YES, otherwise return NO.. Right Shift: A single circular rotation of the string in which the last character becomes the first character and all other characters are shifted to the right. smallest = largest = s.substring(0, k); this line is initializing the first set o substring in both so that it can be compared with the next one because of this only we have started loop from 1 Delete For example, the substrings of abc are a, b, c, ab, bc, and abc. Please let me know the better solution. The second line contains an integer denoting . For example, if string ‘s two distinct characters are x and y, then valid examples could be xyxyx or yxyxy but not xxyy or xyyx. Explanation 0. for (int i = 0; i < n; i++) count [str [i]]++; int max_distinct = 0; for (int i = 0; i < NO_OF_CHARS; i++) if (count [i] != 0) max_distinct++; return max_distinct; } int … For example, ball < cat, dog < dorm, Happy < happy, Zoo < ball. These are the 5 unique substrings of "aac". Sherlock considers a string to be valid if all characters of the string appear the same number of times. Totally, 8 unique strings are present in the set S. The lexicographically 3rd smallest string in S is "aab" and the lexicographically 8th smallest string in S is "c". // Given a string, find out the lexicographically smallest and largest substring of length . Since a substring can be a minimum of size 1 and at max the size of the smallest substring, then we can derive that if they have a letter in common they have a substring in common. Given an array of integers, find and print the minimum absolute difference between any two elements in the array. Given a string, , and an integer, , complete the function so that it finds the lexicographically smallest and largest substrings of length . Solving HackerRank Problem: Two Characters using Java.
