Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters.
Please note that the string does not contain any non-printable characters.
Input: "Hello, my name is John" Output: 5
class Solution:
def countSegments(self, s: str) -> int:
cnt = 0
for i in range(len(s)):
if not s[i].isspace() and (i == 0 or s[i - 1].isspace()):
cnt += 1
return cnt
