There is a prism whose sum of the number of edges, faces, and vertices is 50. How many edges of the pyramid have the same base shape as the prism?
50 2 [OP_SUB] 2 3 [OP_ADD] 1 [OP_ADD] [OP_DIV] 2 [OP_MUL]
var_a = 50
var_b = 2
var_c = var_a - var_b
var_d = 2
var_e = 3
var_f = var_d + var_e
var_g = 1
var_h = var_f + var_g
var_i = var_c / var_h
var_j = 2
var_k = var_i * var_j
print(int(var_k))
