Keep It Simple, Stupid PerlMonks

 Need Help??
Easy,

First: start \$cnt as \$n*\$n instead of 1.
Second: change while loop to continue until \$cnt is not greater then 0.
Third: decrement \$cnt everywhere it was incremented before.

```#!/usr/bin/perl -w

use strict;

print "Enter n: ";
chomp(my \$n = <>);

my @shiza;
my \$firstD = my \$secondD = 0;
my \$cnt    = \$n*\$n;
my \$inc     = 1;

while (\$cnt > 0) {
while (!\$shiza[\$firstD][\$secondD] && \$secondD < \$n && \$inc == 1) {
\$shiza[\$firstD][\$secondD] = \$cnt;
\$secondD++ unless(\$shiza[\$firstD][\$secondD+1] || (\$secondD+1) >=
+ \$n);
\$cnt--;
}
\$firstD++;

while (!\$shiza[\$firstD][\$secondD] && \$firstD < \$n && \$inc == 1) {
\$shiza[\$firstD][\$secondD] = \$cnt;
\$firstD++ unless(\$shiza[\$firstD+1][\$secondD] || (\$firstD+1) >= \$
+n);
\$cnt--;
}
\$secondD--;
\$inc = 0;

while (!\$shiza[\$firstD][\$secondD] && \$secondD >= 0 && \$inc == 0) {
\$shiza[\$firstD][\$secondD] = \$cnt;
\$secondD-- unless(\$shiza[\$firstD][\$secondD-1] || (\$secondD-1) <
+0);
\$cnt--;
}
\$firstD--;

while (!\$shiza[\$firstD][\$secondD] && \$firstD >= 0 && \$inc == 0) {
\$shiza[\$firstD][\$secondD] = \$cnt;
\$firstD-- unless(\$shiza[\$firstD-1][\$secondD] || (\$firstD-1) < 0)
+;
\$cnt--;
}
\$secondD++;
\$inc = 1;
}

for (@shiza) {
for (@{\$_}) {
print "\$_\t" if(\$_);
}
print "\n";
}

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

• Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
• Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
