Hello Programmers, In this post, you will learn how to solve HackerRank Matching {x, y} Repetitions Solution. This problem is a part of the Regex HackerRank 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 Regex HackerRank Solutions using CPP, JAVA, PYTHON, JavaScript & PHP Programming Languages.
HackerRank Matching {x, y} Repetitions Solution
{x, y}
The {x,y} tool will match between x and y (both inclusive) repetitions of character/character class/group.
For Example:
w{3,5} : It will match the character w 3, 4 or 5 times.
[xyz]{5,} : It will match the character x, y or z 5 or more times.
\d{1, 4} : It will match any digits 1, 2, 3, or 4 times.
Task
You have a test string S.
Your task is to write a regex that will match S using the following conditions:
- S should begin with 1 or 2
digits. - After that, S should have 3 or more
letters(both lowercase and uppercase). - Then S should end with up to 3
.symbol(s). You can end with 0 to 3.symbol(s), inclusively.
Note
This is a regex only challenge. You are not required to write any code.
You have to fill the regex pattern in the blank (_________).
