Idea: If we were to fill 0 in front of the number , we would find that the N-bit all 10 binary number is actually N from 0 to 9 of the full array. That is to say, we arrange each digit of the number from 0 to 9, and we get all the 10 binary numbers. 1 /**2 *ch Storing numbers3 *n n Number of digits4 *index Count Value5 **/6 Private functionNum (ch:array,n:int,index:int):void7 {8 if(index==N)9 　　 {Ten Trace (CH); One 　　 return; A 　　 } - 　　

items, the item is 1 heavy 10 lbs, the value is 60 CNY; the item 2 heavy 20 lbs, the value is 100 CNY; the item 3 heavy 30 lbs, the value is 120 RMB. Therefore, since we can choose to install only one part, we can calculate the unit value of each item, item 1 is 6 yuan per pound, item 2 is meibang 5 yuan, item 3 is 4 RMB per pound. According to the greedy strategy, item
