An hourglass in an array is a portion shaped like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code> a b c\n   d\n e f g<\/code><\/pre>\n\n\n\n<p>For example, if we create an hourglass using the number 1 within an array full of zeros, it may look like this:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code> 1 1 1 0 0 0\n 0 1 0 0 0 0\n 1 1 1 0 0 0\n 0 0 0 0 0 0\n 0 0 0 0 0 0\n 0 0 0 0 0 0<\/code><\/pre>\n\n\n\n<p>Actually, there are many hourglasses in the array above. The three leftmost hourglasses are the following:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code> 1 1 1     1 1 0     1 0 0\n   1         0         0\n 1 1 1     1 1 0     1 0 0<\/code><\/pre>\n\n\n\n<p>The sum of an hourglass is the sum of all the numbers within it. The sum for the hourglasses above are 7, 4, and 2, respectively.<\/p>\n\n\n\n<p>In this problem you have to print the largest sum among all the hourglasses in the array.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Input_Format\"><\/span><strong>Input Format<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>There will be exactly <strong>6 <\/strong>lines, each containing <strong>6 <\/strong>integers seperated by spaces.
