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 = int(input())
a = input()
с1 = 0
с2 = 0
с3 = 0
if len(a) != n:
    print('WRONG INPUT')
for i in range(n):
    if a[i] == 1:
        1c += 1
    elif a[i] == 2:
        2c += 1
    else:
        3c += 1
if (c1 >= c2) and (c1 >= c3):
    print(c2 + c3)
elif (c2 >= c1) and (c2 >= c3):
    print(c1 + c3)
else:
    print(c1 + c2)
