By following a special series of instructions (the procedure) it is possible to find ant value in a list of
venues that are sorted in ascending order. This is a useful procedure.
In the procedure you will see reference to 5 special keywords: Items, Nemo, Focus, Position and Count.
In the procedure each of these keywords actually represent a value, and the value might change during
the procedure. You should make a note of the value of each keyword, and update your notes each time
these values change.
Here is a suggested method for keeping track of the keyword values: Use a table like the one below with
a column for each keyword. The procedure changes the value in a keyword by making a statement like
“Count is 1”. This means you should place “1” in the Count column, in the first row, as in the example
below. if the value later changes, write it onto next row in the same column. The current value in the
keyword will always be the last entry in that column.
Items Nemo Focus Position Count
Part 1 – Fix the procedure
But – I left the paper with the procedure in my pocket when my jeans were washed, and now some
details have been erased or smudged. The procedure I now have is listed below, and the parts that I
cannot read are marked like this:_________. Please fill answers in on these lines.
1. Items is the number of Items in the List.
2. Nemo is the Value of an item to be found.
3. Count is 1.
4. Focus is 2.
5. Position =Item divided by focus, rounded to an integer.
6. Skip to Position in the list
7. If Nemo is equal to the value at Position, then go to line __________.
8. Increase Count by 1.
9. If Focus is less than Items, then double the value of Focus.
10. If Nemo is less than the value at Position, then go to line ____________.
11. If Nemo is greater than the value at Position, then go to line __________.
12. Position is Position minus (Items divided by Focus, rounded to an integer)
