Capitalize Word

L1 Easy Strings

Concept

Rebuilding a string from parts — a singled-out first character plus the rest — is a core string manipulation habit.

Return s with only its first character capitalized. If s is empty, return an empty string.

Examples

▸ s = "swift"

→ "Swift"

▸ s = "Swift"

→ "Swift"

▸ s = ""

→ ""

Progressive Hints

Hint 1 · Nudge

You're rebuilding the word from two pieces: the first letter, and everything after it.

Hint 2 · Plan

Handle the empty string first. Uppercase the first character, then attach the rest of the string unchanged. Return the rebuilt string.

Hint 3 · Approach

If s is empty return empty. Else return uppercase(first character) with the remaining characters appended.
