A1023. Breed Counting--Silver

Farmer John's $N$ cows, conveniently numbered $1 \ldots N$, are all standing
in a row (they seem to do so often that it now takes very little prompting
from Farmer John to line them up). Each cow has a breed ID: 1 for Holsteins, 2
for Guernseys, and 3 for Jerseys. Farmer John would like your help counting
the number of cows of each breed that lie within certain intervals of the
ordering.

The first line of input contains $N$ and $Q$ ($1 \leq N \leq 100,000$, $1 \leq
Q \leq 100,000$).
The next $N$ lines contain an integer that is either 1, 2, or 3, giving the
breed ID of a single cow in the ordering.
The next $Q$ lines describe a query in the form of two integers $a, b$ ($a
\leq b$).

For each of the $Q$ queries $(a,b)$, print a line containing three numbers:
the number of cows numbered $a \ldots b$ that are Holsteins (breed 1),
Guernseys (breed 2), and Jerseys (breed 3).
