There is a given sequence of integers *a*<sub class="lower-index">1</sub>, *a*<sub class="lower-index">2</sub>, ..., *a*<sub class="lower-index">*n*</sub>, where every number is from 1 to 3 inclusively. You have to replace the minimum number of numbers in it so that all the numbers in the sequence are equal to each other.
The first line contains an integer *n* (1 ≤ *n* ≤ 10<sup class="upper-index">6</sup>). The second line contains a sequence of integers *a*<sub class="lower-index">1</sub>, *a*<sub class="lower-index">2</sub>, ..., *a*<sub class="lower-index">*n*</sub> (1 ≤ *a*<sub class="lower-index">*i*</sub> ≤ 3).
n, num1, num2, num3 = int(input()), 0, 0, 0

for item in [int(item) for item in input().split(' ')]:
    if item == 1:
        num1 += 1
    elif item == 2:
        num2 += 1
    else:
        num3 += 1

if num1 < num2:
    t = num1
    num1 = num2
    num2 = t
if num1 < num3:
    t = num1
    num1 = num3
    num3 = t

print(num2 + num3)
