Question
What will be the value of `x` after the following
pseudo-code execution? ```   x = 0   data = [10, 20, 30]   for item in data:     if item > 15:       x = x + item     else:       x = x - item   ```Solution
 Dry Run:       `x = 0`       `item = 10`: `10 > 15` is false. `x = 0 - 10 = -10`       `item = 20`: `20 > 15` is true. `x = -10 + 20 = 10`       `item = 30`: `30 > 15` is true. `x = 10 + 30 = 40`       Final `x = 40`
