# Longest Interval Containing One Number

You are given a list of unique integers `nums`

. Return the size of the largest inclusive interval `[start, end]`

such that it contains exactly one number in `nums`

.

**Constraints**

`1 ≤ n ≤ 100,000`

where`n`

is the length of`nums`

`1 ≤ start ≤ end ≤ 100,000`

## Examples

### Example 1

**Input**

- nums =
`[10, 5, 19]`

**Output**

- answer =
`99990`

**Explanation**

The largest interval that contains one number is `[11, 100000]`

which contains `19`

.

### Example 2

**Input**

- nums =
`[5, 50000, 90000]`

**Output**

- answer =
`89994`

**Explanation**

The largest interval that contains one number is `[6, 89999]`

which contains `50,000`
