Word slips: Total receipt
Inputs
line is text. A character is one letter, digit, space, or punctuation mark.
Your tasks
- Create a list
wordLengths. Readlinefrom left to right. Here, a word is a group of characters with no spaces inside it. Record the length of each word. Ignore extra spaces before, after, or between words. For "a cat",wordLengthsis [1, 3]. - Add up every number in
wordLengths. Store the sum intotal. - Complete
wordSlipsTotalReceiptso it returnstotal. Return it, do not print it.
Example
If line is "am ffr", then wordLengths is [2, 3] and wordSlipsTotalReceipt returns 5.
Rules
- If
wordLengthsis empty,totalis 0.
Test data
TEST DATA 1: line is "twwxq heeey".
TEST DATA 2: line is "WW wWW".
Examples
Input: line = "twwxq heeey" Output: 10
wordLengths is [5, 5]. Add its numbers to get 10. Return 10.
Input: line = "WW wWW" Output: 5
wordLengths is [2, 3]. Add its numbers to get 5. Return 5.
Input: line = "" Output: 0
wordLengths is []. Add its numbers to get 0. Return 0.
Input limits
- 0 <= input size <= 64.
- Answers fit in a signed 32-bit integer: -2,147,483,648 through 2,147,483,647.
- The text uses ASCII characters (a basic character set). Only an ordinary space separates words.
Efficiency goal
Big-O describes how the work or memory needed grows as the input gets larger.
Efficiency goal: time O(n); extra memory, including the helper list, O(n). n is the input length. These labels describe how work and memory grow with the input.
Practice focus
Build wordLengths first, then return exactly what the tasks ask for. Follow the order, keep repeated values when the rule says so, and check the empty case.
