There are N natural numbers. These natural numbers are consecutive from 1 to N, and the sum of even numbers in these numbers is 90 and the sum of odd numbers in these numbers is 100. What is the value of N?
100 90 [OP_SUB] 2 [OP_MUL] 1 [OP_SUB]
var_a = 100
var_b = 90
var_c = var_a - var_b
var_d = 2
var_e = var_c * var_d
var_f = 1
var_g = var_e - var_f
print(int(var_g))
