The 3rd-grade students from Sangyeon's school decided to plant one flower at an interval of 4 meters (m) on both sides of the 68-meter (m) road to create a flower path. How many flowers do they need? (Note that flowers must be planted at both ends of the road.)
68 4 [OP_DIV] 2 [OP_MUL] 2 [OP_ADD]
var_a = 68
var_b = 4
var_c = var_a / var_b
var_d = 2
var_e = var_c * var_d
var_f = 2
var_g = var_e + var_f
print(int(var_g))
