Answer:
# the terminal display waiting for the user to enter the input
# the received input is assigned to user_input
user_input = input()
# the user_input is splitted based on space and is assigned to integerlist
integerlist = user_input.split(" ")
# the last element in the integerlist is assigned as threshold
threshold = int(integerlist[len(integerlist) - 1])
# a for loop that loop from index 1 to second to the last element in the list
# the loop compare each element with the threshold
# if element is less than threshold, it is displayed
# the loop start from index 1 because index 0 represent number of element
for i in range(1, (len(integerlist) - 1)):
if int(integerlist[i]) < threshold:
print(integerlist[i], sep="")
