We have 4 teams:
Time 1 | Time 2 | Time 3 | Time 4
I would like to know how to automatically build a list of possible match combinations between these teams.
Example:
Time 1 x Time 2 | Time 1 x Time 3 | Time 1 x Time 4 | ...
I'm having problems with logic for the application.
To count the games, you need to make a simple combination:
function combinacaoSimples(n, p) {
return (fatorial(n) / (fatorial(p) * fatorial(n-p)));
}
function fatorial(n) {
if(n === 0 || n === 1) {
return 1;
}
for(var i = n; i > 0; --i) {
n *= i;
}
return n;
}
combinacaoSimples(4, 2);
For a list of possible combinations:
var i, j, x = [ "Time 1", "Time 2", "Time 3", "Time 4" ],
combinations = [];
for(i = 0; i < x.length; ++i) {
for(j = i + 1; j < x.length; ++j) {
combinations.push([ x[i], x[j] ]);
}
}
