Short Problem Definition:
Alice wrote a sequence of words in CamelCase as a string of letters, , having the following properties:
- It is a concatenation of one or more words consisting of English letters.
- All letters in the first word are lowercase.
- For each of the subsequent words, the first letter is uppercase and rest of the letters are lowercase.
Given s , print the number of words in s on a new line.
For example, s = OneTwoThree . There are 3 words in the string.
time complexity is
space complexity is
Since the input always has at least 1 character, we can assume that there will always be at least one word. Each upper case later identifies the next word. So the result is number of capital letters + 1.
s = raw_input().strip() cnt = 1 for c in s: if c.isupper(): cnt += 1 print cnt
