Question

Write a program to receive a string from the user and compares the first and second half of the word and prints “First and Second Half Same” or “First and Second Half Different”. If the length of the word is odd, ignore the middle letter.

For example:

Run 1:

Enter a word: abcdabc

First and Second Half Same

Run 2:

Enter a word: abcde

First and Second Half Different

Hint: use the Math.floor() and length() to get the halves of the string and use the equals() to perform the similarity check inside if-else statement.

Write a program that reads three different integers from the users and prints “all the same” if they are all equal, “all different”, if three numbers are different and “neither” for all other cases.

For example:

Enter first number: 3

Enter first number: 2

Enter first number: 6

All Different.

Write a program that reads three different floating point numbers from the users and prints the largest of those three:

For example:

First number: 2.36

Second number: 2.99

Third number: 2.78

Largest: 2.99
