I am going to distribute 12 basketballs to 3 students, Jungkook, Jimin, and Hoseok. If each student receives at least one ball, how many different ways can the balls be distributed?
3 12 [OP_ADD] 3 1 [OP_MUL] [OP_SUB] 1 [OP_SUB] 12 3 1 [OP_MUL] [OP_SUB] [OP_COMB]
var_a = 3
var_b = 12
var_c = var_a + var_b
var_d = 3
var_e = 1
var_f = var_d * var_e
var_g = var_c - var_f
var_h = 1
var_i = var_g - var_h
var_j = 12
var_k = 3
var_l = 1
var_m = var_k * var_l
var_n = var_j - var_m
var_o = 1
var_i = int(var_i)
var_n = int(var_n)
for i, elem in enumerate(range(var_n)):
    var_o = var_o * (var_i-i)
for i, elem in enumerate(range(var_n)):
    var_o = var_o / (i+1)
print(int(var_o))
