### Objective

Given a list of numbers -

- How many numbers are larger than the previous one?
- How many sliding window sums are larger than the previous ones

### Puzzle Input

The puzzle input was a list of integers

```
199
200
208
210
200
207
240
269
260
263
```

So the first step was to parse the input into a list of integer. The code below uses a utility function *data* to read the list of numbers

`nums: list[int] = list(data(1, int))`

### Part 1

How many measurements were larger than the previous one

```
def day1_1(nums):
return quantify(map(lambda i: nums[i] > nums[i - 1],
range(1, len(nums))
)
)
```

### Part 2

How many sliding windows of 3 were larger than the previous one

```
def day1_2(nums):
return quantify(map(lambda i:
sum(nums[i - 3:i]) > sum(nums[i - 4: i - 1]),
range(4, len(nums) + 1)
)
)
```
