A game js version (Joseph's ring problem)

This is also an old question. I had a heated discussion on this question in the garden. At that time, I sought to solve it with oo. Now that someone has come up with it, I took some time to write my own ideas:
Copy codeThe Code is as follows:
<Script type = "text/javascript">
Var a_game = function (pNum ){
Var players = [];
For (var I = 1; I <= pNum; I ++ ){
Players. push (I );
}
Var flag = 0;
While (players. length> 1 ){
Var outPlayerNum = 0, len = players. length;
For (var I = 0; I <len; I ++ ){
Flag ++;
If (flag = 3 ){
Flag = 0;
Document. writeln ("outbound:" + players [I-outPlayerNum]);
Players. splice (I-outPlayerNum, 1 );
OutPlayerNum ++;
}
}
}
Return players [0];
};
Document. writeln ("<br/> remaining:" + a_game (100 ));
</Script>

The result is as follows:
Copy codeThe Code is as follows:
Out: 3 out: 6 out: 9 out: 12 out: 15 out: 18 out: 21 out: 24 out: 27 out: 30 out: 33 out: 36 out: 39: 42: 45: 48: 51: 54: 57: 60: 63: 66: 69: 72: 75: 78 out: 81 out: 84 out: 87 out: 90 out: 93 out: 96 out: 99 out: 2 out: 7 out: 11 Out: 16 out: 20 out: 25: 29: 34: 38: 43: 47: 52: 56: 61: 65: 70: 74: 79: 83 out: 88 out: 92 out: 97 out: 1 out: 8 out: 14 out: 22 out: 28 out: 35 out: 41 out: 49 out: 55 out: 62 out: 68 out: 76 out: 82 out: 89 out: 95 out: 4 out: 13 out: 23 out: 32 out: 44 out: 53 out: 64 out: 73 out: 85 out: 94 out: 5 out: 19 out: 37 out: 50 out: 67 out: 80 out: 98 out: 17 out: 40 out: 59 out: 86: 10: 46: 77: 26: 71: 31: 100: 58
