# Intervals Intersecting at Point

You are given a two-dimensional list of integers `intervals`

and an integer `point`

. Each element contains `[start, end]`

represents an inclusive interval.

Return the number of intervals that are intersecting at `point`

.

**Constraints**

`n ≤ 100,000`

where`n`

is the length of`intervals`

## Examples

### Example 1

**Input**

- intervals =

```
[[ 1, 5],
[ 3, 9],
[ 4, 8],
[10,13]]
```

- point =
`4`

**Output**

- answer =
`3`

**Explanation**

At time `4`

, there are `3`

intervals that are intersecting: `[1, 5], [3, 9], [4, 8]`
