I made a square by arranging go stones without gaps. If the number of go stones on the perimeter is 52, how many go stones are on the outermost of one side?
52 4 [OP_SUB] 4 [OP_DIV] 2 [OP_ADD]
var_a = 52
var_b = 4
var_c = var_a - var_b
var_d = 4
var_e = var_c / var_d
var_f = 2
var_g = var_e + var_f
print(int(var_g))
