package com.example.midterm_problem2;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    private TextView Original_text;

    private EditText Third;

    private TextView Text_logg;

    String myText;
    String final_result;
    String num_str1,num_str2,num_str3;
    int num1, num2, num3;

    String new_word;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Original_text= (TextView)findViewById(R.id.original_text);
