In the context of designing a system that offers a file management capability, e.g., OneDrive, there are some constraints on the acceptable file names. The following three characters {*,$, :} in addition to spaces are not allowed in file names. If any of these four characters appears in a file name, it is replaced by a hyphen (-). Examples: "new file" → "new-file" "important$file" → "important-file" "abcdefghijklm.txt" → "abc-def-gh-ij-klm.txt" "exam.doc" → "exam.doc" i. Design an algorithm that takes a file name as a string and returns a modified name replacing the prohibited characters with hyphens. Use pseudocode to describe your algorithm. Define all operations that are used in your algorithm. ii. What is the runtime complexity of your algorithm?
