Question

Harry Potter is on a mission to destroy You-Know-Who's Horcruxes. The first Horcrux that he encountered in the Chamber of Secrets is Tom Riddle's diary. The diary was with Ginny and it forced her to open the Chamber of Secrets. Harry wants to know the different people who had ever possessed the diary to make sure they are not under its influence.
He has names of n people who possessed the diary in order. You need to tell, for each person, if he/she possessed the diary at some point before or not.
Formally, for a name s_i in the i-th line, output "YES" (without quotes) if there exists an index j such that s_i = s_j and j < i, otherwise, output "NO" (without quotes).

Input
First line of input contains an integer n (1 ≤ n ≤ 100) — the number of names in the list.
Next n lines each contain a string si, consisting of lowercase English letters. The length of each string is between 1 and 100.

Output
Output n lines each containing either "YES" or "NO" (without quotes), depending on whether this string was already present in the stream or not.
You can print each letter in any case (upper or lower).

Answer 1

n=int(input())#read n value from user
l=[]
for i in range(n):
l.append(input())#append names to list l
  
res=[]
for i in range(n):#for each name check if he/she is already in the stream
if l[i] in res:
print("YES")
else:
print("NO")
res.append(l[i])
