Problem type

cheesecake is preparing to write some math tests. Since math does not come easily to cheesecake, he is also preparing for the worst: not getting perfect on each one. Whenever cheesecake botches a test, the experience emotionally tilts him — it throws him off his game. He has to write $N$ $N$ tests, knowing that test $i$ $i$ will tilt him by $T_i$ $T_{i}$ degrees (naturally, tilt is mathematically represented in degrees).

Remembering the wise words of his math teacher, cheesecake recalls that once you tilt a full 360 degrees, you are back to normal — that is, a tilt of $360^\circ$ $360^{\circ}$ is equal to no (zero) tilt.

cheesecake would like to know just how disappointed he will feel after writing all his tests. To this end, he has asked you to determine his final tilt.

Input Specification

The first line of input will contain the integer $N$ $N$ $(1 \le N \le 100)$ $(1 \leq N \leq 100)$ , the number of math tests cheesecake will write.
The next $N$ $N$ lines of input will each contain the decimal tilt of a test, with line $i$ $i$ representing $T_i$ $T_{i}$ $(0.0 \le T_i \le 10.0^{15})$ $(0.0 \leq T_{i} \leq {10.0}^{15})$ . Each decimal will be written with exactly six digits after the decimal point.

Output Specification

A single decimal value in the range $[0, 360)$ $[0, 360)$ ; cheesecake's tilt after writing all his tests. Answers will be considered correct if they are within an absolute or relative error less than or equal to $10^{-5}$ $10^{- 5}$ .

Sample Input

2
0.000000
361.000000

Sample Output

Copy

1.000000

Explanation

cheesecake was well prepared for his first test, but his second test had some tricky logarithms that tilted him by $361^\circ$ $361^{\circ}$ . This is equivalent to a tilt of $1^\circ$ $1^{\circ}$ .

Can someone take a look at my code I don't really understand why it isn't working I'm guessing it has to do on the problems output specification but I am not sure

The input specification for this problem was underspecified, so the statement has been updated to clarify the precision with which these decimals are expressed. The checker for this problem remains unmodified, in spite of the mismatch between the input precision of $10^{-6}$ $10^{- 6}$ and the output precision of $10^{-5}$ $10^{- 5}$ .

One test case has been added and most unlocked solutions have been rejudged. After the migration to Java 17 completes, all remaining Java submissions will be rejudged.

Using Turing tilts me by 399 gradians

I'm tilted 0 degrees.

Reading your solution tilts me so hard I capsized.

(As does this math format)
