package com.example.hp.myhello;
import android.content.res.Configuration;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;

public class MainActivity extends AppCompatActivity {
     String msg = "Android :";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.d(msg, "On created Method()");
    }

    protected void onStart() {
        super.onStart();
        Log.d(msg, "On start method() ");
    }

    protected void onResume(){
        super.onResume();
        Log.d(msg,"On the Resume method()");
    }

    protected void onPause()
    {
        super.onPause();
        Log.d(msg,"on the Pause method()");
    }

    protected void onStop()
    {
        super.onStop();
        Log.d(msg,"on the stop method()");
    }

    protected void onRestart()
    {
        super.onRestart();
        Log.d(msg,"on the OnRestart method()");
    }

    protected void onDestroy()
    {
        super.onDestroy();
        Log.d(msg,"on the Destroy method()");
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        if(newConfig.orientation==Configuration.ORIENTATION_LANDSCAPE)
        {
            Log.d(msg,"Welocome to Landscape !!");
        }else if(newConfig.orientation==Configuration.ORIENTATION_PORTRAIT){
            Log.d(msg,"Welcome to Portrait !!!");
        }
   }
}

Sum of Digit is Pallindrome or not

  Sum of Digit is Pallindrome or not Given a number N.Find if the digit sum(or sum of digits) of N is a Palindrome number or not. Note:A Palindrome number is a number which stays the same when reversed.Example- 121,131,7 etc. Example 1: Input: N=56 Output: 1 Explanation: The digit sum of 56 is 5+6=11. Since, 11 is a palindrome number.Thus, answer is 1. Example 2: Input: N=98 Output: 0 Explanation: The digit sum of 98 is 9+8=17. Since 17 is not a palindrome,thus, answer is 0. Your Task: You don't need to read input or print aything.Your Task is to complete the function isDigitSumPalindrome() which takes a number N as input parameter and returns 1 if the Digit sum of N is a palindrome.Otherwise it returns 0. Expected Time Complexi...

Closest Number

Closest Number Basic Accuracy: 11.21% Submissions: 1615 Points: 1 Given non-zero two integers N and M . The problem is to find the number closest to N and divisible by M . If there are more than one such number, then output the one having maximum absolute value .   Example 1: Input: N = 13 , M = 4 Output: 12 Explanation: 12 is the Closest Number to 13 which is divisible by 4. Example 2: Input: N = -15 , M = 6 Output: -18 Explanation: -12 and -18 are both similarly close to -15 and divisible by 6. but -18 has the maximum absolute value. So, Output is -18   Your Task: You don't need to read input or print anyth...
