PROGRAMMING:Tumor diagnosis
In the diagnosis of tumor diseases, it is very important to calculate the tumor volume. Given the suspected tumor area marked in the scan section of the lesion, please calculate the volume of the tumor.
###Input format:
The first line of input gives four positive integers: $$M $$, $$n $$, $$l $$, $$t $$, where $$M $$and $$n $$are the size of each slice (that is, each slice is a pixel matrix of $$m / times n $). The maximum resolution is $$1286 times 128 $)$$ L $$($$Le 60 $$) is the number of slices$$ T $$is an integer threshold (if the connected volume of the suspected tumor is less than $$t $, the small block is ignored).
Finally, $$l $$slices are given. Each image is represented by a matrix of $$m / times n $, which is composed of 0 and 1, where 1 is the pixel of suspected tumor and 0 is the normal pixel. Since the slice thickness can be regarded as a constant, we only need to count the number of 1 in the continuum to get the volume. The trouble is that there may be multiple tumors. At this time, we only count those whose volume is not less than $$t $. Two pixels are considered "connected" if they have a common section, as shown in the figure below, all six red pixels are connected to the blue pixels.

###Output format:
Output the total volume of the tumor in one line.
###Input example:
```in
3 4 5 2
1 1 1 1
1 1 1 1
1 1 1 1
0 0 1 1
0 0 1 1
0 0 1 1
1 0 1 1
0 1 0 0
0 0 0 0
1 0 1 1
0 0 0 0
0 0 0 0
0 0 0 1
0 0 0 1
1 0 0 0
```
###Output example:
```out
twenty-six
```
