題目描述
Farmer John suffered a terrible loss when giant Australian cockroaches ate the entirety of his hay inventory, leaving him with nothing to feed the cows. He hitched up his wagon with capacity C (1 <= C <= 50,000) cubic units and sauntered over to Farmer Don's to get some hay before the cows miss a meal.
Farmer Don had a wide variety of H (1 <= H <= 5,000) hay bales for sale, each with its own volume (1 <= V_i <= C). Bales of hay, you know, are somewhat flexible and can be jammed into the oddest of spaces in a wagon.
FJ carefully evaluates the volumes so that he can figure out the largest amount of hay he can purchase for his cows.
Given the volume constraint and a list of bales to buy, what is the greatest volume of hay FJ can purchase? He can't purchase partial bales, of course. Each input line (after the first) lists a single bale FJ can buy.
約翰遭受了重大的損失：蟑螂吃掉了他所有的乾草，留下一群饑餓的牛．他乘著容量為C(1≤C≤50000)個單位的馬車，去頓因家買一些乾草． 頓因有H(1≤H≤5000)包乾草，每一包都有它的體積Vi(l≤Vi≤C).約翰只能整包購買，
他最多可以運回多少體積的乾草呢？
