vector u1 = (x = 1, y = 3)
vector v1 = (x = 3, y = 1)
Vaihdetaan vektorit keskenään
vector u1 = (x = 1, y = 3)
vector v1 = (x = 3, y = 1)
Vaihdetaan vektorit takaisin
vector u1 = (x = 3, y = 1)
vector v1 = (x = 1, y = 3)
Vaihdetaan vektorit vielä kerran
vector u1 = (x = 1, y = 3)
vector v1 = (x = 1, y = 3)
