    Python 3 solution:

    queue = []

number_of_queries = int(input())

for _ in range(number_of_queries):
    query_and_data = input()
    query_and_data_split = query_and_data.split()
    if len(query_and_data_split) == 2:
        queue += [int(query_and_data_split[1])]
    elif int(query_and_data_split[0]) == 2:
        queue = queue[1:]
    elif int(query_and_data_split[0]) == 3:
        print(queue[0])
