You are the owner of a coworking space like WeWork and your office building is rectangular. Your team just built wall partitions to create mini offices for startups. This office campus is represented by a 2D array of 1s (floor spaces) and 0s (walls). Each point on this array is a one foot by one foot square. You need to calculate the number of offices. A single office is bordered by walls and is constructed by placing floors next to each other, horizontally and/or vertically. Two 1s adjacent to each other horizontally or vertically are always part of the same office.

numOffices() has one parameter:

For some of our templates, we have handled parsing for you. If we do not provide you a parsing function, you will need to parse the input directly. In this problem, our input format is as follows:

4

5

11110

11010

11000

00000

Return the number of valid offices in the grid.

Example numOffices() Input

grid:

[[1, 1, 0, 0, 0],

[1, 1, 0, 0, 0],

[0, 0, 1, 0, 0],

[0, 0, 0, 1, 1]]

Example Output

3

Solution

**Functions**numOffices() has one parameter:

- grid: a 2D grid/array of 1s and 0s

**Input Format**For some of our templates, we have handled parsing for you. If we do not provide you a parsing function, you will need to parse the input directly. In this problem, our input format is as follows:

- The first line is the number of rows in the 2D array
- The second line is the number of columns in the 2D array
- The rest of the input contains the data to be processed

4

5

11110

11010

11000

00000

**Expected Output**Return the number of valid offices in the grid.

**Constraints**- Assume all four edges of the grid are all surrounded by walls.
- Assume that the bounds of the array are the following:
- The total amount of elements in the array: width x height <= 10^6

**Example**Example numOffices() Input

grid:

[[1, 1, 0, 0, 0],

[1, 1, 0, 0, 0],

[0, 0, 1, 0, 0],

[0, 0, 0, 1, 1]]

Example Output

3

Solution

**There's 3 offices in this grid, one made of four 1s on the top left, one made of one 1 in the middle, and one made of two 1s in the bottom right.**
