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 = input()
i1 = 0
i2 = 0
i3 = 0
s = list(map(int,input().split()))
for j in s:
   if(j==1):
      i1 = i1+1
   if(j==2):
      i2 = i2+1
   if(j==3):
      i3=i3+1
if(i2>=i3 and i2>=i1):
   print(i3+i1)
elif(i3>=i2 and i3>=i1):
   print(i2+i1)

   print(i3+i2)
