Problem Statement
A university is implementing an admission system that evaluates applicants based on their exam score, interview score, and document submission status. The admission decision follows these rules:
- If the exam score is 90 or higher, the applicant is admitted regardless of other factors
- If the exam score is 80 or higher but less than 90, the applicant is admitted only if they have submitted documents and their interview score is 85 or higher
- If the exam score is 70 or higher but less than 80, the applicant is admitted only if they have submitted documents and their interview score is 90 or higher
- If the exam score is below 70, the applicant is not admitted regardless of other factors
- If documents are not submitted, the applicant cannot be admitted under any circumstances
Your task is to determine whether an applicant is admitted or not based on these criteria.
