Complexity: time complexity is O(N) space complexity is O(1) Execution: This is a pythonesque solution by Jay Mistry. If there had been more moves available, they could have been eliminated by performing multiple deletions on an empty string. if a becomes 9 we can just break the loop and print "YES". 1 <= roll[i] <= 10^5, Question source : Airtel Interview experience | Set 1 (FTE On-campus), Simple Approach : keep on changing the characters of string for every roll[i] Rolling means increasing ASCII value of character, like rolling ‘z’ would result in ‘a’, rolling ‘b’ would result in ‘c’, etc. generate link and share the link here. This article is contributed by Mandeep Singh. For example, if string it does contain hackerrank, but does not. Counting Valleys. c) Finally, the problem is marked as "Easy" by the HackerRank folks One wrong approach to follow is to attempt to actually delete characters: you'll end up with massive permutations and it will become intractable. Given a string s and an array roll where roll[i] represents rolling first roll[i] characters in string. We first divide the string into even and odd number as we can see that in the string "Hacker," H is in even place, and a is in an odd place and so on. If we reorder the first string as , it no longer contains the subsequence due to ordering.
