Question

Given a line of text as input, output the number of characters excluding spaces, periods, or commas.

Answer 1

Answer:

import java.util.Scanner;

public class ANot {

   public static void main(String[] args) {

       Scanner in = new Scanner(System.in);

       System.out.println("Please enter a string of words");

       String n = in.nextLine();

       int count = 0;

       for (int i=0; i<n.length(); i++){

           if((n.charAt(i) != '.') &&(n.charAt(i) != ',') && (n.charAt(i) != ' ')){

               count++;

           }

       }

       System.out.println(count);

   }

}

Explanation:

1. Prompt User to input the string and assign to a variable
2. SET count =0.
3. Using a for loop iterate over the string
4.  if((n.charAt(i) != '.') &&(n.charAt(i) != ',') && (n.charAt(i) != ' ')) then count =count +1.
5.     PRINT count.

Answer 2

Answer:

user_text = input()

import re

str1= input("21 ")

pattern = '[a-zA-Z]'

count=0

i=0

while(i<=len(str1)-1):

  result = re.match(pattern, str1)

  if (result):

      count+=1

  else:

      continue

  i+=1

print("String Length:",count)
