🏆 [M💙 Challenge] Substring Reversal

Question

Monday Blue 💙 Challenge Series #1

Write a program to accept both { string } and { length } to perform reverse on each of the substrings of the given length.

Here are the test cases of "123456789":-

☑ Length 1 output: "123456789"

☑ Length 2 output: " 214365879"

☑ Length 3 output: "321654987"

Assumption: 1 ≤ length ≤ string's length

Happy Coding!!! 😁💻

Answer 2

@ysraelcon Another creative use of regex! You reminds me about the comic strip by xkcd below and it seems almost anything can be solved by regex. 😂

Answer 5

@Calvin Good job! We need a general approach to accept any length of substring with the constraint above by using one function only. I believe you can do it! 😄

Answer 6

Here's my own C# implementation! ✌

LINQ One-Liner〰
string.Concat(
Enumerable.Range(0, input.Length)
.GroupBy(i => i / length)
.Select(g => string.concat(
g.Select(i => input[i])
.Reverse())))

Yup it's a LINQ solution again~ Enjoy! ❤

Answer 9

@noobcøder You're welcome! 😄

Well the best answer was selected after every week, perhaps you're too busy to get notified about it. 😂

Glad that there are people still interested with the challenge since I BUMP it unintentionally by standardizing the tags across my post.

Thank you everyone again! 👍
