begin

 var (p, s) := (1, 1);

 for var i := 2 to 6 do

 begin

   p *= i;

   s += p

 end;

 s.Println

end.

873

Answer 2

S=1+2+6+24+120+720=853

Answer 3

To compute the value of S, which is the sum of factorials from 1! to 6!, we need to calculate each factorial and then add them together. Let's break it down step by step:

1! = 1 2! = 2 × 1 = 2 3! = 3 × 2 × 1 = 6 4! = 4 × 3 × 2 × 1 = 24 5! = 5 × 4 × 3 × 2 × 1 = 120 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720

Now, let's add these factorials together:

S = 1! + 2! + 3! + 4! + 5! + 6! S = 1 + 2 + 6 + 24 + 120 + 720 S = 873

So, the value of S is 873.
