We are going to divide the road into 16 sections and install flags on the road except for both ends. It takes 9 seconds to plant one flag. We take a rest for 5 seconds after placing another flag. Find the time it takes to place all the flags.
16 1 [OP_SUB] 9 5 [OP_ADD] [OP_MUL]
var_a = 16
var_b = 1
var_c = var_a - var_b
var_d = 9
var_e = 5
var_f = var_d + var_e
var_g = var_c * var_f
print(int(var_g))
