Chunks Between Spaces

Easy

You are given a string line. A chunk is a maximal run of consecutive non-space characters. Return the number of chunks in the line. Spaces may come in runs, and the line may start or end with spaces.

Example 1

line="  ok,  let's   go! " → 3

The space-free chunks are ok,, let's and go!. Extra spaces at the edges and in between change nothing.

Example 2

line="2+2=4" → 1

There are no spaces, so the whole line is one chunk.

Example 3

line="   " → 0

Only spaces, so there are no chunks.

Example 4

line="" → 0

Constraints

0 ≤ len(line) ≤ 300
line consists of English letters, digits, spaces and the characters !@#$%^&*()_+-=',.:
