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 } - for(vari:int=0;i) - { thech[index]=i; -Nu
