Write the structure and formula of following organic compounds- (a) CO2 (b) H20 (c) NH3 (d) CH4​

Answer:

They are similar but all sides and angles of square are equal but a rectangle have pair of two equal sides

Step-by-step explanation:

Answer:

import java.util.Scanner;

class palindrome

{

static String reverse(String s)

{

char[] letters = new char[s.length()];

 int ind = 0;

 for(int i = s.length() - 1; i >= 0; i--)

 {

 letters[ind] = s.charAt(i);

 ind++;

 }

 String reversed = "";

  for(int i = 0; i < s.length(); i++)

  {

  reversed = reversed + letters[i];

  }

return reversed;

}

static boolean isPalindrome(String str)

{

 if(reverse(str).equals(str))

 {

 return true;

 }

 else

 {

 return false;

 }

}

public static void main(String[] args)

{

Scanner sc = new Scanner(System.in);

System.out.print("Enter a string:");

String x = sc.nextLine();

 if(isPalindrome(x))

 {

 System.out.println(x + " is a palindrome");

 }

 else

 {

 System.out.println(x + " is not a palindrome");

 }

}

}
