Calculating $lim_{nto infty}{frac{frac{n}{1} + frac{n-1}{2} + frac{n-2}{3} + … + frac{2}{n-1} +...

Compute $lim_{ntoinfty}frac{tfrac{n}{1}+tfrac{n-1}{2}+dots+tfrac{2}{n-1}+tfrac{1}{n}}{ln(n!)}$ [closed]

I have tried to use the Stolz theorem and calculate $lim_{nto infty}{frac{a_{n+1}-a_n}{b_{n+1}-b_n}}$ and i have reached $lim_{nto infty}{frac{1 + frac{1}{2} + frac{1}{3} + ... + frac{1}{n-2} + frac{1}{n-1} + frac{1}{n}}{ln (n+1)}}$ but I do not know how to continue. Could someone help me? Thanks in advance.

Hint: See the "Rate of divergence" section of the Wikipedia article about the harmonic series, or the definition of the Euler-Mascheroni constant.

So i can rewrite the top part as $ln(n) + gamma + frac{1}{2n}$?

No....but you can approximate it by that (or better still, find upper and lower bounds and use the squeeze lemma).
