Question

下列程序計(jì)算的數(shù)學(xué)式是(    )

n=input(“n=”);

T=1;s=0;i=1;

while i＜=n

    T=T  *2^i;

    s=s+1/T;

    i=i+1;

end

disp(s)

A.1+2+3+…+n                                  B.1!+2!+3!+…+n!

C.1!+1/2!+1/3!+…+1/n!                           D.1+1/2+1/3+…+1/n

Answer 1

答案：C

思路分析:本題是一個(gè)遞推累加問(wèn)題,由T=T*i經(jīng)過(guò)循環(huán)依次得到1!,2!,3!,…,n!,由s=s+1/T實(shí)現(xiàn)累加.故選C.
