SOLVE:

static > int minPos(Iterable l){ // write using fold. No other loops permitted. }

Fold Methods:

static V foldLeft(V e, Iterable l, BiFunction f){ for(U x: l)

{ e = f.apply(e, x); } return e; }

static V foldRight(V e, Iterable l, BiFunction f){ for(U x: l)

{ e = f.apply(x, e); } return e; }
