• A decision arrived at by following instructions

• Step-by-step instructions used to solve a problem

• A computer program that follows a chart

Which of these pseudocode algorithms matches this flowchart?

• input a

  b <- 1

  c <- 1

  IF (a>1)

  d <- b + c

  c <- b

  d <- c

  a <- a - 1

  ENDIF

  output c

• input a

  b <- 1

  WHILE (a>1)

  d <- b + c

  c <- b

  d <- c

  a <- a - 1

  ENDWHILE

  output c

• input a

Some pseudocode to manipulate a numeric list is given below:

input list

a <- first_item_in_list

WHILE NOT end of list

b <- next item in the list

IF a > b

a <- b

ENDIF

ENDWHILE

output a

• average(list)

• max(list)

• min(list)

• search list for a

A bubble sort algorithm will loop until?

• We have completed an entire run of comparing each item with the next in the list, and have made no changes during the run.

• We have compared each item with the item next to it and swapped them if needed.
