Description

In this problem we are interested in maintaining a set of integers that supports two operations:
  1. add(x): add a number x (1 ≤ x ≤ 106) to the set.
  2. count(a, b): count the number of elements within the range [a, b] (1 ≤ a ≤ b ≤ 106).
Write a program to perform Q queries of type 1 or 2.
En este problema se desea mantener un conjunto de enteros que soporta dos operaciones:
  1. add(x): Adiciona el número x (1 ≤ x ≤ 1000000) al conjunto.
  2. count(a, b): Contar el número de elementos en el rango [a, b] (1 ≤ a ≤ b ≤ 1000000).
Escriba un programa para ejecutar Q consultas de tipo 1 o 2.
