# Balloons

The seller has **n** balloons. Each balloon has some color. However, recently Three Fat Men issued a decree permitting to sell the balls of a single color. In order not to break the law, but not to lose profits, the seller decided to repaint some of his balls.

Write a program to determine the minimum number of repainting.

#### Input

First line contains the number of balloons **n** (**1** ≤ **n** ≤ `10`

). Second line contains ^{5}**n** integers in the range from **1** to **9**, determining the colors of the balls (**1** - blue, **2** - green, **3** - cyan, **4** - red, **5** - rose, **6** - yellow, **7** - gray, **8** - black, **9** - white).

#### Output

Print the minimum number of balloons to repaint so that all balls have the same color.
