Ideas similar to Quick sortUsing two pointers, one pointer to the front element, and the other pointer to the last element;The first pointer moves to the right until an even number is encountered, and the second pointer moves forward until it encounters an odd number and then swaps the two data.It ends when the left hand pointer meets the right pointer, and then returns the array.1 #!/usr/bin/env Python32 3 defJi_first_ou (ary):4Indexa,indexb = 0,len (ary)-15 whileIndexa Indexb:6

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

Use JavaScript to take float type two digits after the decimal point, example 22.127456 to 22.13, how to do? 1. Discard the fractional part and keep the whole number of parts parseint (5/2) 2. Take up the whole, there are decimal numbers on the whole part plus 1 Math.ceil (5/2) 3, rounded. Math.Round (5/2) 4, take the whole down. Math.floor (5/2) Alternative ways to 1. The Dumbest Way The code is as follows Copy Code
