Yesterday, when i'm idle and curious, i'm wondering about prime number. Since i'm suck at math, i find it with the suck way. I'm using nodejs because its simple to scripting and cheap on resource. Here is the code :
var stash = [];
for (var i=1; i<100; i++) {
var tmp = {ke: i, loop: []};
for (var k=1; k<100; k++) {
if ((i%k == 0)) {
tmp.loop.push(k);
}
}
stash.push(tmp);
}
for (var u=0; u<stash.length; u++) {
if ( stash[u].loop.length == 2 ) {
console.log(stash[u].ke);
}
}
