6. Problem of the Week
Farmer John needs to sell a chunk of his land. Unfortunately, the land he sells inevitably affects the N cows (1 <= N <= 100,000) that graze on it. Given the start point, Ps, and end point, Pe, of grazing in meters (1 <= Ps < Pe <= 250,000) for each cow, answer Farmer John’s Q questions (1 <= Q <= 100,000). Each question will ask how many cows are affected by cutting out a piece of land from one point, Qs, to another, Qe (1 <= Qs < Qe <= 250,000).

7. Problem of the Week (cont.)
Input: Line 1: Space-separated integers N and Q Lines 2 … N + 1: Ps and Pe for each cow on the farm Lines N + 2 … N + Q + 1: Space-separated integers Qs and Qe
Output: Lines 1 … Q: One integer representing the answer to each question
