Friday, September 18, 2015 Problem I found this page around 2014 and after then I exercise my brain for FUN. Since a = 9 means we have found all letters of hackerrank. char ch; scanf ("%c", &ch); printf ("%c", ch); This piece of code prints the character . Rolling means increasing ASCII value of character, like rolling ‘z’ would result in ‘a’, rolling ‘b’ would result in ‘c’, etc. We say that a string contains the word hackerrank if a subsequence of its characters spell the word hackerrank.Remeber that a subsequence maintains the order of characters selected from a sequence. Complexity: time complexity is O(N) space complexity is O(1) Execution: This is a pythonesque solution by Jay Mistry. * - means "0 or more instances of the preceding regex token", So it matches any word that has hackerrank in it such as, eval(ez_write_tag([[300,250],'thepoorcoder_com-box-4','ezslot_8',108,'0','0']));Assume our string is, Initially a = 0 means "hackerrank"[0] = "h", In our for loop once we find a "h" we will increase a. For example abc < abd, because c < d.Also z > yyy because z > y.If one string is an exact prefix of the other it is lexicographically smaller, e.g., gh < ghij. Efficient Approach : Better approach will be create a array and store total roll operation to be performed on each character in it, and then traverse the string and perform the roll operation. These are my solutions and may not be the best solution. //Printing Tokens in C - Hacker Rank Solution #include #include #include int main () ... the above hole problem statement is given by hackerrank.com but the solution is generated by the codeworld19 authority if any of the query regarding this … ...
