HUAWEI OD Machine Test-Explore Plot Establishment-2022Q4 Volume A-Py/Java/JS

Given a plot of n*m, which is equivalent to a two-dimensional array of n*m, the value of each element represents the power generation of this small plot; seek to build a power station with a square side length c on this plot, and generate electricity The number of plots whose quantity satisfies the target electricity k.

Enter a description:

The first line is four positive integers separated by spaces, representing n, m, ck respectively

The following n lines of integers represent the power generation of each plot

Output description:

Output the number of plots that meet the criteria

Example:

enter:

2 5 2 6 // nmck, each line below is the power generation per grid of n*m plots

1 3 4 5 8

2 3 6 7 1

output:

4
