If you are trying to decorate a fruit basket with 5 different fruits, including 2 pineapples, what is the number of cases that pineapples are placed at both ends?
5 2 [OP_SUB] 5 2 [OP_SUB] [OP_PERM] 2 [OP_MUL]
var_a = 5
var_b = 2
var_c = var_a - var_b
var_d = 5
var_e = 2
var_f = var_d - var_e
var_g = 1
var_c = int(var_c)
var_f = int(var_f)
for i, elem in enumerate(range(var_f)):
    var_g = var_g * (var_c-i)
var_h = 2
var_i = var_g * var_h
print(int(var_i))
