Breed Counting
Farmer John's N cows, conveniently numbered 1…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.

Input Format
The first line of input contains N and Q (1≤N≤100,000, 1≤Q≤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≤b).
Output Format
For each of the Q queries (a,b), print a line containing three numbers: the number of cows numbered a…b that are Holsteins (breed 1), Guernseys (breed 2), and Jerseys (breed 3).
