What is the following pseudocode trying to achieve?

```
INPUT n
counter = 0
s = 0
WHILE counter < n
 INPUT num
 s = s + num
 counter = counter + 1
OUTPUT s
```

What is the following pseudocode trying to achieve?
<pre><code>INPUT n
counter = 0
s = 0
WHILE counter &lt; n
 INPUT num
 s = s + num
 counter = counter + 1
OUTPUT s
</code></pre>

```
INPUT n
counter = 1
WHILE counter <= 10
 OUTPUT 1 * counter
 counter = counter + 1
```

```
INPUT n
counter = 1
WHILE counter <= 10
 OUTPUT n * counter
 counter = counter + 1

```

```
INPUT n
counter = 1
WHILE counter <= 10
 counter = counter + 1
 OUTPUT n * counter

```

Which of the following pseudocodes is correct for outputting the multiplication table of a number *n*, i.e., *n* x 1 to *n* x 100?

Which of the following pseudocodes is correct for outputting the multiplication table of a number n, i.e., n x 1 to n x 100?

What is the output of the following pseudocode?

```
counter = 0
first = 0
second = 1
temp = 0
WHILE counter <= 3
 OUTPUT first
 temp = first + second
 first = second
 second = temp
 counter = counter + 1
```

What is the output of the following pseudocode?
<pre><code>counter = 0
first = 0
second = 1
temp = 0
WHILE counter &lt;= 3
 OUTPUT first
 temp = first + second
 first = second
 second = temp
 counter = counter + 1
</code></pre>
