A: It varies, but a common formula is: (passed_level + 1) * 20 . If you pass Level 0 (index 0), you get 20. Level 1 gives 40, Level 2 gives 60, Level 3 gives 80. Passing score is usually 50, so you need Level 2 (60) or a combination of lower levels? No – wait, check your campus's scale. Most require Level 3 (80) minus penalty? The safe bet: Pass a Level 3 exercise.

: A program that takes a string and replaces all instances of one character with another.

This seems easy until you realize you must return NULL if min >= max . Beginners often forget that negative ranges are allowed (e.g., min = -5 , max = 5 is valid).
