Here we need to find the starting index of minimum rotation and then print the rotation.1) Initially assume 0 to be current min starting index.2) Loop through i = 1 to n-1. a) For each i compare sequence starting at i with current min starting index b) If sequence starting at i is lexicographically smaller, update current min starting index.Here is pseudo-code for algorithm function findIndexForSmallestSequence(S, n): result = 0 for i = 1:n-1 if (sequence beginning at i < sequence beginning at result) result = i end if end for return resultHere is implementation of above algorithm. JavaScript // Javascript program to find lexicographically // smallest sequence with rotations. // Function to compare lexicographically // two sequence with different starting // indexes. It returns true if sequence // beginning with y is lexicographically // greater. function compareSeq(S, x, y, n) { for (let i = 0; i < n; i++) { if (S[x] < S[y]) return false; else if (S[x] > S[y]) return true; x = (x + 1) % n; y = (y + 1) % n; } return true; } // Function to find starting index // of lexicographically smallest sequence function smallestSequence(S, n) { let index = 0; for (let i = 1; i < n; i++) // if new sequence is smaller if (compareSeq(S, index, i, n)) // change index of current min index = i; return index; } // Function to print lexicographically // smallest sequence function printSmallestSequence(str, n) { let S = str.split(""); let starting_index = smallestSequence(S, n); for (let i = 0; i < n; i++) console.log(S[(starting_index + i) % n]); } // driver code let S = "DCACBCAA"; let n = 8; printSmallestSequence(S, n); OutputA A D C A C B C Complexity Analysis:Time Complexity : O(n^2) Auxiliary Space : O(1)Please refer complete article on Lexicographically smallest rotated sequence | Set 2 for more details!

Given a word, find a lexicographically smaller permutation of it. For example, lexicographically smaller permutation of â4321â is â4312â and the next smaller permutation of â4312â is â4231â. If the string is sorted in ascending order, the next lexicographically smaller permutation doesnât exist. Rec 11 min read Make a lexicographically smallest palindrome with minimal changes Given a string S. Print the lexicographically smallest string possible. You can make minimal changes to the characters in the string and you can permute the string. Examples: Input : S = "aabc" Output : "abba" Input : S = "aabcd" Output : "abcba" Explanation 1:Change the last index "c" to "b", it be 11 min read Lexicographically minimum string rotation | Set 1 Write code to find lexicographic minimum in a circular array, e.g. for the array BCABDADAB, the lexicographic minimum is ABBCABDAD.Source: Google Written Test More Examples: Input: GEEKSQUIZ Output: EEKSQUIZG Input: GFG Output: FGG Input: GEEKSFORGEEKS Output: EEKSFORGEEKSG Following is a simple sol 5 min read Like
