How to use these solutions

Read the input format, follow the dry run, and then type or copy the program into the compiler. Change the sample input to check your understanding. These are learning solutions based on the syllabus supplied, not an official examination answer key.

Examples use standard C17. Read each program's stated limits. String positions are 1-based for display; C array indexes are 0-based.
