# Summary Ranges Lab

In this lab, you will implement a function called `summaryRanges`

that takes a **sorted unique** integer array `nums`

as its input and returns the **smallest sorted** list of ranges that **cover all the numbers in the array exactly**. This means that each element of `nums`

should be covered by exactly one of the ranges, and there should be no integer `x`

such that `x`

is in one of the ranges but not in `nums`

.

A **range** `[a,b]`

is the set of all integers from `a`

to `b`

(inclusive). Each range `[a,b]`

in the list should be output as:

`"a->b"`

if`a != b`

`"a"`

if`a == b`

You will be using ESM import/export for this lab, and you will be required to complete the evaluation script provided.

## Lab Description

Implement a function `summaryRanges`

:

`/** * @param {number[]} nums * @return {string[]} */ export function summaryRanges(nums) { }`

### Constraints:

`0 <= nums.length <= 20`

`-231 <= nums[i] <= 231 - 1`

- All the values of
`nums`

are**unique**. `nums`

is sorted in ascending order.

### Example 1:

**Input:** nums = [0,1,2,4,5,7]

**Output:** ["0->2","4->5","7"]

**Explanation:** The ranges are:

- [0,2] --> "0->2"
- [4,5] --> "4->5"
- [7,7] --> "7"

### Example 2:

**Input:** nums = [0,2,3,4,6,8,9]

**Output:** ["0","2->4","6","8->9"]

**Explanation:** The ranges are:

- [0,0] --> "0"
- [2,4] --> "2->4"
- [6,6] --> "6"
- [8,9] --> "8->9"

## Challenges

- Implement the
`summaryRanges`

function. - Complete evaluation script for initial testing and further challenges.
- Ensure that there are no errors and that the code executes as expected.
