Java

Example 1:
Input : s ="()";
Output : true
Example 2:
Input: s = "() [] {}"
Output : true
Example 3:
 Input : s = "(]"
Output : false
Example 4:
Input : s = "([)]"
Output : fasle
Example 5: 
Input : s = "{[] }"
Output : true

The Condition should match s ="()" true condition. or s ="(" should return false … same for other conditions as well

Hi guys I created a project in android studio which has 2 types of login system the

 1. Sign in with email and password 

 2. Login with phone number

I have a problem in login with phone number 

I have 3 activities in project which in 

 1. I am taking the the login with email and password

 2. Is I am taking the login with phone number 

 3. I am checking if the email is verified or not

So if the email is verified the person can go to app inside 

But when I login with phone number it go to the 3rd activitiy to the email verification but I want it go to the app not to the verify email activity 

Here is my code for main activity


----------

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

        mAuth = FirebaseAuth.getInstance();
        currentUser = mAuth.getCurrentUser();

        myViewPager = (ViewPager) findViewById(R.id.main_tabs_pager);
        myTabsaccessorAdopter = new TabsAccessorAdopter(getSupportFragmentManager());
        myViewPager.setAdapter(myTabsaccessorAdopter);

        myTabLayout = (TabLayout) findViewById(R.id.main_tabs);
        myTabLayout.setupWithViewPager(myViewPager);
    }

    @Override
    protected void onStart()
    {
        super.onStart();
        if (currentUser == null)
        {
            SendUserToLoginActivity();
        }
        else
        {
            if(!currentUser.isEmailVerified())
            {
                SendUserToVerifyEmailActivity();
            }
        }
    }

    private void SendUserToLoginActivity()
    {
        Intent loginIntent = new Intent(MainActivity.this,LoginActivity.class);
        startActivity(loginIntent);
    }

    private void SendUserToVerifyEmailActivity()
    {
        Intent verifyEmailIntent  = new Intent(MainActivity.this,VerifyEmailActivity.class);

3. Modify the code from the last week’s theoretical lecture (HelloWorldPanel, 
HelloWorldFrame) to make a frame and a panel that show your full name
at each corner of the frame. Let the names be (MyNamePanel, 
MyNameFrame) and choose whatever formats you want.
