'int' object has no attribute 'append'
<p>when I run this code then following error is encountered, I am new to programming and I know I have bunch of useless arrays.I don't know where my error is as I have declared j as an array. I am completely out of Ideas. I would really appreciate if you could please help me out to find solution to the problem.</p>
