3.7.11 programming 1! + 2! + 3! +... 20! Value

 

Public class p3711 {
Public static void main (string [] ARGs ){
Long sum = 0, n = 1;
For (INT I = 1; I <= 20; I ++ ){
N = 1;
For (Int J = 1; j <= I; j ++ ){
N * = J;
}
Sum + = N;
System. Out. Print ("I =" + I + "sum =" + sum + "/N ");
}

}
}

 

LaterCommunityThe Forum asked, and according to the train of thought, I improved it :)

 

Public Class P3711 {
Public Static Void Main (string [] ARGs ){
Long Sum = 0 , N = 1 ;
For ( Int I = 1 ; I <= 20 ; I ++ ){
N * = I ;
Sum + = N;
System. Out. Print ( " I = " + I + " Sum = " + Sum + " /N " );
}

}
