Hello Programmers, In this post, you will learn how to solve HackerRank Split the Phone Numbers 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 Split the Phone Numbers Solution
Problem
There is a list of phone numbers which needs the attention of a text processing expert. As an expert in regular expressions, you are being roped in for the task. A phone number directory can reveal a lot such as country codes and local area codes. The only constraint is that one should know how to process it correctly.
A Phone number is of the following format
[Country code]-[Local Area Code]–[Number]
There might either be a ‘-‘ ( ascii value 45), or a ‘ ‘ ( space, ascii value 32) between the segments
Where the country and local area codes can have 1-3 numerals each and the number section can have 4-10 numerals each.
And so, if we tried to apply the a regular expression with groups on this phone number: 1-425–9854706
We’d get:
Group 1 = 1
Group 2 = 425
Group 3 = 9854706
You will be provided a list of N phone numbers which conform to the pattern described above. Your task is to split it into the country code, local area code and the number.
Input Format
N, where N is the number of tests.
This will be followed by N lines containing N phone numbers in the format specified above.
Constraints
1 <= N <= 20
There might either be a hyphen, or a space between the segments
The country and local area codes can have 1–3 numerals each and the number section can have 4-10 numerals each.
Output Format
Your output will contain N lines.
CountryCode=[Country Code],LocalAreaCode=[Local Area Code],Number=[Number]
Recommended Technique
This problem can be solved in many ways, however, try to solve it using regular expressions and groups in order to gain a hands on practice of the concepts involved.
Sample Input
2
1 877 2638277
91-011-23413627
Sample Output
CountryCode=1,LocalAreaCode=877,Number=2638277
CountryCode=91,LocalAreaCode=011,Number=23413627
