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).
input()
count1,count2,count3 = 0,0,0
for item in [int(it) for it in input().split(' ')]:
    if item == 1:
        count1 += 1
    elif item == 2:
        count2 += 1
    else:
        count3 += 1

print(count1 + count2 + count3 - max(count1,count2,count3))
