L1 Easy Strings

Concept

Each character of a Swift string can be inspected individually, and characters know about their own case.

Return true if the first character of s is an uppercase letter. An empty string or a string starting with a non-letter returns false.

Examples

▸ s = "Swift"

→ true

▸ s = "hello"

→ false

▸ s = "123"

→ false

Progressive Hints

Hint 1 · Nudge

Look only at the very first character and ask it about its case.

Hint 2 · Plan

Handle the empty string by returning false. Otherwise check whether the first character is an uppercase letter and return that.

Hint 3 · Approach

If s is empty return false. Else return whether s's first character is uppercase.
