I want to draw vertical lines for loops and if statement. Kindly help me out and also I didn't use any specific package

• Welcome to TeX SX! Yet the algorithmis defined by a package… – Bernard Jul 14 '17 at 13:05
• yeah!! Only algorithm package, However, it didn't worked for me can you please help me out. – Smith Jul 14 '17 at 13:10
• I can try. Would you be kind enough to post a full compilable code? – Bernard Jul 14 '17 at 13:20
• It is full code except for package {\usepackage{algorithm} However, I will also edit the code. – Smith Jul 14 '17 at 13:30

You have to load algorithm2e to do that easily:

\usepackage[utf8]{inputenc}
\usepackage[ruled, lined, longend, linesnumbered]{algorithm2e}
