1) Input text
2) Compare each character with:
    letter
    punctuation
3) Output with changes

using System;
using System.Collections.Generic;
namespace AntiCAPS {
    public class Program {
        public static void Main(string[] args) {
            bool _newSentence = true;
            string message = Console.In.ReadToEnd().ToLower();
            List<char> punctuation = new List<char>(new char[] { '!', '.', '?' });
            for (int iterable = 0; iterable < message.Length; iterable++) {
                if ((int)message[iterable] >= 97 && (int)message[iterable] <= 122) {
                    if (_newSentence) {
                        Console.Write(Char.ToUpper(message[iterable]));

как сделать ввод на питоне в этой задаче? how to make python input in this task?

Example 1:

WHAT??????????????????????


Example 2:

??????????????????????

2 test. why?

Does anybody had Acces Violation? And if so , how did you fix it?

If you wa, try these

HELLO. WORLD

- IS IT CORRECT?
- YES, IT IS.

Sorry for my bad English.
I use

    int ch;
    while ((ch = System.in.read()) != -1) {
        // my solution
        System.out.print(<some char>);
    }
    System.out.println();

But I get WA #1 with or without last code line. I also used System.out.flush (without last line), but it do not help me.

Can you help me?

HHHHHH.KJDFDKJ(newline)

I've been struggling hard to overcome WA4 and WA9...
In the problem statement, it says "Sentences in a message consist of words, spaces and punctuation marks".
Then I've made these test cases and got AC in one go... :)
Try these cases if u get WA...

Case 1:
WHO ARE UUUUUUUUUUUUUUUUUUU
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU?
CANT U SEE IT ?
Ans:
Who are uuuuuuuuuuuuuuuuuuu
uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu?
Cant u see it ?

Case 2:
 WHO ARE UUUUUUUUUUUUUUUUUUU
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU?
CANT U SEE IT ?
Ans:
 Who are uuuuuuuuuuuuuuuuuuu
uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu?
Cant u see it ?

(It looks same to case 1, but it has an initial space character in the first line and I think this was causing WA9 for me...)

Case 3:
AND BEING CARELESS, WE ARE DESTROYING THE EARTH.
?????
WHO ARE UUUUUUUUUUUUUUUUUUU
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU?
CANT U SEE IT ?

WHY DID U DO THIS?
UUUUUUUU
UUUUUUUU IDIOT.
BYE.

Ans:
And being careless, we are destroying the earth.
?????
Who are uuuuuuuuuuuuuuuuuuu
uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu?
Cant u see it ?

why did u do this?
Uuuuuuuu
uuuuuuuu idiot.
Bye.

Case 4:
...ARE U THERE STILL?
PLEASE, ANSWER MEEEEEEEEE ,
ANSWER ME , ANSWER ME...
PLEASE
Ans:
...Are u there still?
Please, answer meeeeeeeee ,
answer me , answer me...
Please



Let me know if any1 finds any error...
Thanks.

I found hah)
