What is the result when the following program is executed?

```ruby
a = ['a','b','c','d','e','f','g','h','i']
print(a[2...-2])
```

What is the result when the following program is executed?
<pre><code class="language-ruby">a = ['a','b','c','d','e','f','g','h','i']
print(a[2...-2])
</code></pre>

What is the output when the following program is executed?

```ruby
a = ['a','b','c','d','e','f','g','h','i']
for i in -2...2
   print(a[i]," ")
end
```


What is the output when the following program is executed?
<pre><code class="language-ruby">a = ['a','b','c','d','e','f','g','h','i']
for i in -2...2
 print(a[i],&quot; &quot;)
end
</code></pre>

What is the output when the following program is executed?

```ruby
a = ['a','b','c','d','e','f','g','h','i']
i = 1
while i < a.length
 print(a[-i]," ")
 i += 2
end
```

What is the output when the following program is executed?
<pre><code class="language-ruby">a = ['a','b','c','d','e','f','g','h','i']
i = 1
while i &lt; a.length
 print(a[-i],&quot; &quot;)
 i += 2
end
</code></pre>

What is the result when the following program is executed?

```ruby
a = ['abcdefghi']
i = 1
while i < a[0].length
 print(a[0][i]," ")
 i += 2
end
```

What is the result when the following program is executed?
<pre><code class="language-ruby">a = ['abcdefghi']
i = 1
while i &lt; a[0].length
 print(a[0][i],&quot; &quot;)
 i += 2
end
</code></pre>

What is the result when the following program is executed?

```ruby
m = [[1,2,3],[4,5,6],[7,8,9]]
s = i = 0
size = 3
while i < size
 j = 0
 while j < size
 s += m[j][i]
 j += 1
 end
 print(s," ")
 i += 1
end
```

What is the result when the following program is executed?
<pre><code class="language-ruby">m = [[1,2,3],[4,5,6],[7,8,9]]
s = i = 0
size = 3
while i &lt; size
 j = 0
 while j &lt; size
 s += m[j][i]
 j += 1
 end
 print(s,&quot; &quot;)
 i += 1
end
