I wrote my program in Pascal cause in C++ it makes me Compilation
Error, I think is right but i get WA :(

type
point = record
          i, j: integer;
        end;
var
p: array[1..1000] of point;
s: array[1..1000] of real;
a: array[1..50,1..50] of longint;
used: array[1..50,1..50] of boolean;
ans, M, N, K: integer;

function dis(x,y:point): real;
var
   ii,jj,hh:real;
begin
    ii := (x.i-y.i)*(x.i-y.i);
    jj := (x.j-y.j)*(x.j-y.j);
    hh := (a[x.i,x.j]-a[y.i,y.j])*(a[x.i,x.j]-a[y.i,y.j]);
    dis:=sqrt(ii+jj+hh);
end;

var
   where:point;
   i, j, l:integer;
   label bad;
begin
      readln(M,N,K);
    for i:=1 to M do
      for j:=1 to N do used[i,j]:=false;
    for i:=1 to M do begin
      for j:=1 to N do read(a[i,j]);
          readln;
        end;
    for l:=1 to K do
        readln(p[l].i,p[l].j,s[l]);
    for l:=1 to K do
        used[p[l].i,p[l].j]:=true;
      ans:=0;
    for i:=1 to M do
       for j:=1 to N do
          if not used[i,j] then begin
             where.i:=i; where.j:=j;
         while a[i,j]<=32000 do begin
                for l:=1 to K do
                if dis(where,p[l])>s[l] then goto bad;
                     inc(a[i,j]);
             inc(ans);
         end;
         bad:
          end;
      write(ans);
end.
