	# Lists

	# Consider a list (list = []). You can perform the following commands:
	# insert i e: Insert integer e at position i.
	# print: Print the list.
	# remove e: Delete the first occurrence of integer e.
	# append e: Insert integer e at the end of the list.
	# sort: Sort the list.
	# pop: Pop the last element from the list.
	# reverse: Reverse the list.

	# Initialize your list and read in the value of n followed by n lines of commands where each command will be of the types listed above.
	# Iterate through each command in order and perform the corresponding operation on your list.

	# Input Format
	# The first line contains an integer, n, denoting the number of commands.
	# Each line i of the n subsequent lines contains one of the commands described above.

	# Constraints
	# The elements added to the list must be integers.

	# Output Format
	# For each command of type print, print the list on a new line.


	# Enter your code here. Read input from STDIN. Print output to STDOUT
	list = []
	n = int(raw_input())
	for i in range(n):
	a = raw_input().split()
	if len(a) == 3:
	eval("list." + a[0] + "(" + a[1] + "," + a[2] + ")")
	elif len(a) == 2:
	eval("list." + a[0] + "(" + a[1] + ")")
	elif a[0] == "print":
	print list
	else:
	eval("list." + a[0] + "()")
