NOTE : Avoid copy and paste the code directly because class name at the start which is in the code i submitted is "example" it may not be same for you because class name must match to file name .. I will provide screenshot for more clarity

Another thing is careful while using if condition without braces . you must follow proper indentation.

You can copy the code but you must need to change the class name to file name

I'm submitting output that i got below

****************** EXAMPLE 1 *****************
x < y
a <= 10023

****************** EXAMPLE 2 *****************
x is even.
x is even.
This statement WILL output.

****************** EXAMPLE 3 *****************
Select an option:
1. Have Time
2. Work Hard
3. Socialize

> 2
Keep it up!

****************** EXAMPLE 4 *****************
You got a A!
You got a B!
You got a C!

****************** EXAMPLE 5 *****************
a is equal to 4!

******************** EXAMPLE 6 *****************
********************* EXAMPLE 7 *****************
a is equal to 483!
That's right -a is equal to 483!

********************* EXAMPLE 8 *****************
b is equal to 483!
That's right -b is equal to 483!

********************* EXAMPLE 9 *****************
Enter first integer: 9
Enter second integer: 3
9 != 3
9 > 3
9 >= 3

********************* EXAMPLE 10 ****************
You passed

If you are new to use code editors remember Numbers on the left side of images are line numbers they are not part of the code

Hope this will be helpful
