Which trucks are overloaded
A dispatch list pairs each truck with its load and its capacity. Count how many trucks are carrying more than their capacity.
- The two lists are the same length and read like parallel records.
- A load exactly equal to capacity is fine.
overCapacity(loads: list<int>, capacity: list<int>) → int
Go needs a compiler and Drill does not host one yet, so this page is the reference rather than an exercise: the problem, worked examples, and the solution in full. To type it out, the same problem runs in Python.
Where you start
func overCapacity(loads []int, capacity []int) int {
}Worked examples
| Call | Result |
|---|---|
overCapacity([]int{10, 20, 30}, []int{8, 20, 40}) | 1 |
overCapacity([]int{1, 2}, []int{9, 9}) | 0 |
overCapacity([]int{10, 10}, []int{4, 4}) | 2 |
overCapacity([]int{}, []int{}) | 0 |
Hint
Iterate the indices and compare.
Reference solution in Go
func overCapacity(loads []int, capacity []int) int {
n := 0
for i := range loads {
if loads[i] > capacity[i] {
n++
}
}
return n
}
