Возможный вариант в C++ #include <iostream> int main() { using namespace std; int N; cout << "Enter N: "; cin >> N; int num; int max = 1; int i; for (i = 0; i < N; ++i) { cout << "Enter #" << i + 1 << " number: "; cin >> num; if ((num - 9) % 10 != 0 && num % 3 == 0) { max = num; break; } } for (int j = i + 1; j < N; ++j) { cout << "Enter #" << j + 1 << " number: "; cin >> num; if ((num - 9) % 10 != 0 && num % 3 == 0) if (num > max) max = num; } if (max != 1) cout << "Max number div by 3 and don't end 9: " << max << endl; else cout << "No numbers div by 3 and don't end 9" << endl; return 0; }
не так уж и трудно, если
program project2;
var
n,a,b,c,i,k,max,min: longint;
inp,outp: text;
begin
assign(inp,'input.txt');
reset(inp);
assign(outp,'output.txt');
rewrite(outp);
readln(inp,n);
max: =0;
min: =0;
c: =0;
for i: =1 to n do
begin
read(f1,a);
if i=1 then
b: =a;
if a> max then
max: =a;
k: =a-c;
c: =a;
if k< 0 then
begin
k: =abs(k);
min: =min+k;
if k> min then
min: =k;
end;
end;
max: =max-b;
write(outp,max,' ',min);
close(inp);
close(outp);
end.
