[Lazarus] some number manipulation

[Curt Carpenter]

I would create a matrix A[i,j] with i = 1,2,3,...31 (31 rows) and 
j=1,2,3,...20 (20 columns).
Initialize the matrix to all zeroes.
Then for each day of the month, if the number "k" occurs in day j, then 
set A[j,k] := 1.
At the end of the month, the sum of the elements in row k will tell you 
how many times k occurred during the month.
Then scan each row of the matrix looking for three or more consecutive 
1's (left as an exercise :-)
