1/1! + 1/2! + 1/3! +... + 1/N !...... Deep feelings

This is an interesting one. I just learned it when I went to school.C LanguageWhen I started my first lesson on data structure, the teacher gave me the following question:
Use programming: 1/1! + 1/2! + 1/3! +... + 1/n!
Then I thought, isn't that easy!

Float S = 0 ;
For ( Int I = 1 ; I <= 34 ; I ++ )
{
Int K = 1 ;
For ( Int J = 1 ; J <= I; j ++ )
K * = J;
S + = 1 / K;
}

When I was proud, the teacher wrote his on the blackboard. Code : Float S = 1 ;
For ( Int I = 2 , J = 1 ; I <= 10 ; I ++ )
{
J=I*J;
S+ =1/J;
}

Every day, every day. At that time, I was very ashamed. He has a loop, and I have two loops. He has done a lot of things repeatedly. From which point I realized that programming has many mysteries and many skills that I need to learn. From this, I figured out thatProgramDo the same job as little as possible.
