Complete the stringReduction function in the editor below. so smallest and largest should be found only among these words. 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'. Lexicographical Order, also known as alphabetic or dictionary order, orders characters as follows: A < B < ... < Y < Z < a < b < ... < y < z. Remember that a subsequence maintains the order of characters selected from a sequence. If we reorder the first string as , it no longer contains the subsequence due to ordering. has a length of , and has a length of ; the sum of their lengths is . More formally, let p[0],p[1],…p[9] be the respective indices of h, a, c, k, e, r, r, a, n, k in string . Now, S = {S1 U S2} = {"a", "aa", "aab", "aac", "ab", "ac", "b", "c"}. We need to apply every roll[i] on string and output final string. 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.

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. Java Solution. For example, abcde becomes eabcd after 1 right shift and deabc after 2 right shifts. I like this problem, so i decided to put my solution on my site.Below is the question and solution… Read More » // Given a string, find out the lexicographically smallest and largest substring of length . String s = "welcometojava"  has the following lexicographically-ordered substrings of length K=3: ["ava","com","elc","eto","jav","lco","met","oja","ome","toj","wel"]. // Input Format // First line will consist a string containing english alphabets which has at most characters. But length of the string is 13 so i<=s.length means i<=13 loop runs 14 times and the substring indexes are also out of bounds due to k+i.So if we subtract k=3 from length i.e i<=s.length-k(3) then i<=10 now the loop runs 11 times as we need and index values of substring are also within limits and hence output. Given a string, , and an integer, , complete the function so that it finds the lexicographically smallest and largest substrings of length . Java Regex. For example, in “aabcbcdb”, the smallest string that contains all the characters is “abcbcd”. To do this, you are allowed to delete zero or more characters in the string. It must return an integer that denotes the length of the shortest string … Problem.
