Reason through the problem and: 1. Restate the problem in plain English 2. Conceptualize a solution first in plain English 3. Write a pseudocode solution 4. Save your solution as solution.py No outside libraries are allowed. [BEGIN PROBLEM] Problem 1: Milk Scheduling [Traditional, 2011] Farmer John has N cows that need to be milked (1 <= N <= 10,000), each of which takes only one unit of time to milk. Being impatient animals, some cows will refuse to be milked if Farmer John waits too long to milk them. More specifically, cow i produces g_i gallons of milk (1 <= g_i <= 1000), but only if she is milked before a deadline at time d_i (1 <= d_i <= 10,000). Time starts at t=0, so at most x total cows can be milked prior to a deadline at time t=x. Please help Farmer John determine the maximum amount of milk that he can obtain if he milks the cows optimally. PROBLEM NAME: msched INPUT FORMAT: * Line 1: The value of N. * Lines 2..1+N: Line i+1 contains the integers g_i and d_i. SAMPLE INPUT: 4 10 3 7 5 8 1 2 1 INPUT DETAILS: There are 4 cows. The first produces 10 gallons of milk if milked by time 3, and so on. OUTPUT FORMAT: * Line 1: The maximum number of gallons of milk Farmer John can obtain. SAMPLE OUTPUT: 25 OUTPUT DETAILS: Farmer John milks cow 3 first, giving up on cow 4 since she cannot be milked by her deadline due to the conflict with cow 3. Farmer John then milks cows 1 and 2.
