Longest Same-Letter Streak

Easy

You get a string text of lowercase English letters. A streak is a run of identical letters standing next to each other. Return the length of the longest streak. A single letter on its own counts as a streak of length 1.

Example 1

text="zzzzaaabzzz" → 4

The longest streak is the four z's at the start; the three a's and the trailing z's are shorter.

Example 2

text="moon" → 2

Only the two o's stand next to each other.

Example 3

text="q" → 1

Constraints
