There are 6 colored pencils, all of different colors, in the pencil case. If you draw two and lend one to the friend in front and the other to the friend in the back, how many possible situations are there?
6 2 [OP_PERM]
var_a = 6
var_b = 2
var_c = 1
var_a = int(var_a)
var_b = int(var_b)
for i, elem in enumerate(range(var_b)):
    var_c = var_c * (var_a-i)
print(int(var_c))
