Adding parentheses is solving the issue. But I am still confused why the error came with the original code? Should I conclude Hackerrank editor uses Busybox awk version in the backend?

I don't know Hackerrank, so can't really tell, but it looks like it.

Hackerrank is coding practice platform based in India. The link to the question is hackerrank.com/challenges/awk-4/problem . Since parentheses is solving the error maybe they are using busybox version only. Thank You for the help.
