## B. Logarithm

Time limit: 1.0 second
Memory limit: 64 MB
Given a set A of N unordered 128-bit numbers. You are to compute a value of the function where Ak is the kth element of A, log10X — the integer part of the decimal logarithm of X. We’ll assume that log100 = 0.

### Input

The first input line contains a number N ≤ 5000. In the following N lines there are 128-bit numbers Ak presented by sets of numbers (a1k, a2k, a3k, a4k), each of them lies in range from 0 to 232-1. The number Ak can be obtained from this set according to the formula
Ak = 296a1k + 264a2k + 232a3k + a4k.

### Output

You are to output the value of the function for the given set.

### Sample
