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 } -
It is recommended that first look at the preface: http://www.wutianqi.com /? P = 2298 Total Directory: http://www.wutianqi.com /? P = 2403 GreedyAlgorithmTo avoid comparison with DP, so we need to know about the previous DP. Greedy algorithms make the selection seem to be the best at present, and we hope to generate a global optimal solution through the local optimal selection. Like summary DP in the previous chapter, I will first give an example of the easiest way to get started, to see if S
