HackerRank Funny String Solution

Hello Programmers, In this post, you will learn how to solve HackerRank Funny String Solution. This problem is a part of the HackerRank Algorithms Series.

One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions. We are going to solve the HackerRank Algorithms problems using C, CPP, JAVA, PYTHON, JavaScript & SCALA Programming Languages.

You can practice and submit all HackerRank problem solutions in one place. Find a solution for other domains and Sub-domain. I.e.

HackerRank Funny String


In this challenge, you will determine whether a string is funny or not. To determine whether a string is funny, create a copy of the string in reverse e.g. abc -> cba. Iterating through each string, compare the absolute difference in the ascii values of the characters at positions 0 and 1, 1 and 2 and so on to the end. If the list of absolute differences is the same for both strings, they are funny.

Determine whether a give string is funny. If it is, return Funny, otherwise return Not Funny.


s = ‘lmnop’

The ordinal values of the charcters are [108, 109, 110, 111, 112]sreverse = ‘ponml’ and the ordinals are [112, 111, 110, 109, 108]. The absolute differences of the adjacent elements for both strings are [1, 1, 1, 1], so the answer is Funny.

Function Description

Complete the funnyString function in the editor below.

funnyString has the following parameter(s):

  • string s: a string to test


  • string: either Funny or Not Funny

Input Format

The first line contains an integer q, the number of queries.
The next q lines each contain a string, s.


  • 1 <= q <= 10
  • 2 <= length of s <= 10000

Sample Input

STDIN Function
—– ——–
2 q = 2
acxz s = ‘acxz’
bcxz s = ‘bcxz’

Sample Output

Not Funny


Let r be the reverse of s.

Test Case 0:
s = acxz, r = zxca
Corresponding ASCII values of characters of the strings:
s = [97. 99, 120, 122] and r = [122, 120, 99, 97]
For both the strings the adjacent difference list is [2, 21, 2].

Test Case 1:
s = bcxzr = zxcb
Corresponding ASCII values of characters of the strings:
s = [98, 99, 120, 122] and r = [122, 120, 99, 98]
The difference list for string s is [1, 21, 2] and for string r is [2, 21, 1].

1. How do you solve the first question in HackerRank?

If you want to solve the first question of Hackerrank then you have to decide which programing language you want to practice i.e C programming, Cpp Programing, or Java programming then you have to start with the first program HELLO WORLD.

2. How do I find my HackerRank ID?

You will receive an email from HackerRank to confirm your access to the ID. Once you have confirmed your email, the entry will show up as verified on the settings page. You will also have an option to “Make primary”. Click on that option. Read more

3. Does HackerRank detect cheating?

yes, HackerRank uses a powerful tool to detect plagiarism in the candidates’ submitted code. The Test report of a candidate highlights any plagiarized portions in the submitted code and helps evaluators to verify the integrity of answers provided in the Test.

4. Does HackerRank use camera?

No for coding practice Hackerrank does not use camera but for companies’ interviews code submission time Hackerrank uses the camera.

5. Should I put HackerRank certificate on resume?

These certificates are useless, and you should not put them on your resume. The experience you gained from getting them is not useless. Use it to build a portfolio, and link to it on your resume. 

6. Can I retake HackerRank test?

The company which sent you the HackerRank Test invite owns your Test submissions and results. It’s their discretion to permit a reattempt for a particular Test. If you wish to retake the test, we recommend that you contact the concerned recruiter who invited you to the Test and request a re-invite. 

7. What is HackerRank?

HackerRank is a tech company that focuses on competitive programming challenges for both consumers and businesses. Developers compete by writing programs according to provided specifications. Wikipedi
