Looping

One can iterate through all the elements of a set, in increasing order, thanks to a loop of the form for (const <variable> of <set>) <block>. It means that the <block> of statements (or a single statement) will be computed once for each <variable> ranging over the elements of the set <set> in increasing order.

Here is an example where the integers in a set are summed up.

function sum_elt (s: set<int>) {

let sum = 0;

for (const e of s) sum = sum + e;

return sum;

};
