Difficulty: Medium

Following the clue, I ended up with a 5 by 5 grid. It asked for K to be excluded.

A B C D E

F G H I J

L M N O P

Q R S T U

V W X Y Z

Coordinates to get the digits are given as row (-) to column (

).

1-3 = C

4-4 = T

2-1 = F

{ = {

4-4 = T

2-3 = H

4-5 = U

3-2 = M

1-2 = B

4-3 = S

_ = _

4-5 = U

3-5 = P

} = }

Combining them gives CTF{THUMBS_UP}

flag CTF{THUMBS_UP}
