A: Security check in websites that want to prevent robots

B: The first 25 contests in codeforces, contests 15, 20, and 21 was unrated, so print NO, otherwise print YES

C: Every testcase will give you n numbers, where n = i-th number of PI, so n1 = 3, n2 = 1, n3 = 4, and so on..

D: Print any number that is guranteed that it won't come in the sequence, for example 0 or -1

E: Print any positive number (I don't know)

F: Print largest prime factor, don't calculate it, just put if

G: The image shows that he is a color blind, n is the length, s1 is what person sees, s2 is what is the real colors. Print YES if the person only sees the red color correctly.

H: Complex probabilities problem, because all the numbers are random

I: Check if the bracket sequence is balanced, Consider letters "bdfhklt" as open bracket, and letters "gjpqy" as closed bracket, ignore other letters

J: Write "please" in any lettercase, and judge will give you AC
