this problem is a classic. i got this one from an interview.
you’re given the string as input consisting solely of (, ),
and any alpha lower case chars a-z.
determine whether the parentheses are balanced.
recentry i have been in interviews to find a new professional opportunity. i got this code challenge from on of those interviews.
what i liked about this particular interview was that the code challenge had progressions/iterations: every time i solved it, the interviewer added constraints or scenarios to support.
the code challenge was to implemente the following function:
/**
* @param header a comma-separated list of languages preferred by the client (in order) `en-US,fr-CA,de-DE`
* @param availableLanguages set of available languages in the platform
* @return the available languages preferred by the client (in order) in the platform
*/
def languages(header: String, availableLanguages: Set[String]): Set[String] = ???
