Python:
n = input("Nhập dãy số nguyên: ").split()
n = [int(i) for i in n]

so_le = [i for i in n if i % 2 != 0]
tong = sum(n)

print("Các số lẻ trong dãy là: ", so_le)
print("Tổng các số trong dãy là: ", tong)

Pascal:

program tongvasole;

const
  MAX_SIZE = 1000;

var
  numbers: array[1..MAX_SIZE] of Integer;
  count, i: Integer;
  total: Integer;
begin
  Write('Nhập số lượng phần tử trong dãy: ');
  ReadLn(count);
  for i := 1 to count do
  begin
    Write('Nhập phần tử thứ ', i, ': ');
    ReadLn(numbers[i]);
  end;

  Write('Các số lẻ trong dãy là: ');
  total := 0;
  for i := 1 to count do
  begin
    if numbers[i] mod 2 <> 0 then
      Write(numbers[i], ' ');
    total := total + numbers[i];
  end;
  WriteLn;

  WriteLn('Tổng các số trong dãy là: ', total);
