434. 求字符串有多少段 Number of Segments in a String

Posted 2020-09-01 Long Long Journey

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.

Example:

Input: "Hello, my name is John"
Output: 5

题意：求字符串有多少被空格分隔的段

public class Solution {
    public int CountSegments(string s) {
        int sum = 0;
        int newIndex = 0;
        for (int i = 0; i < s.Length; i++) {
            if (s[i] != ‘ ‘) {
                newIndex = i;
                while (newIndex < s.Length && s[newIndex] != ‘ ‘) {
                    newIndex++;
                }
                sum++;
                i = newIndex;
            }
        }
        return sum;
    }
}
