    left_list = []
right_list = []

for line in file:
    split_line = line.split()
    left_list.append(int(split_line[0]))
    right_list.append(int(split_line[1]))

sorted_left = sorted(left_list)
sorted_right = sorted(right_list)
distance = []
for left, right in zip(sorted_left, sorted_right):
    distance.append(abs(left - right))

total = sum(distance)

print(total)
    Part 2 
    file = open('input.txt', 'r')
left_list = []
right_list = []

for line in file:
    split_line = line.split()
    left_list.append(int(split_line[0]))
    right_list.append(int(split_line[1]))

sim_score = 0
for item in left_list:
    sim = right_list.count(item)
    sim_score += (sim * item)

print(sim_score)
