What property of the duplicates program allows it to handle arbitrarily large input streams?

• A. It stores input lines in an array/slice before processing
• B. It reads input incrementally using a line-by-line scanner
• C. It relies on buffered output
• D. It sorts input before counting

Why does the duplicates program print results after reading all input?

• A. Because maps can only be iterated once
• B. Because duplicates cannot be detected until all input is read
• C. Because standard input must be closed first
• D. Because the final counts are only known after scanning completes

What is a key limitation of the current duplicates program?

• A. It cannot read from standard input
• B. It cannot detect duplicates
• C. It must store all distinct lines in memory
• D. It only works without special characters in the text

Why is streaming I/O (i.e., input/output) important?

• A. It simplifies syntax
• B. It improves readability
• C. It allows programs to handle large or unbounded data
• D. It eliminates the need for error handling
