Decimal Galore

by CodeChum Admin

We've been dealing with integers too much, it's time for decimals to shine!

Instructions:

1. Input five decimal numbers in one line.
2. Print out the decimal numbers in one line, separated by spaces, and make sure you only print up to 1 decimal place.
3. Add the first four decimal numbers and check if their sum is greater than the fifth decimal number. Print out "Yes" if they are.

Input

A line containing five decimal numbers separated by a space.

1.1·1.2·1.3·1.4·1.1

Output

The first line contains all the inputted decimal numbers separated by a space.

The second line contains a string which is the result.

1.1·1.2·1.3·1.4·1.1
Yes

Are Strings Created Equally?

by CodeChum Admin

Do you believe in doppelgangers? Well they are very much possible with strings! Check if the two given strings are the same or not.

2. Print out the strings in one line, separate them with a \.
3. Check whether the two strings are equal, print out "Equal" if they are.

Input

Two lines containing a string on each.

hello
hello

Output

The first line contains the two inputted strings separated by a \.

The second line contains a string result.

hello\hello
Equal
