Section: Algorithm
7. s] A transport consultant has created a file of information about trips collected from
individuals who have participated in a survey. This information includes start_time and
end_time variables. One of the items contained in the file is the duration of each trip (that
is, end_time – start_time) in minutes. The consultant is trying to work out how to calculate
the number of trips with duration greater than 60 minutes (that is, how many trips take
longer than an hour) and requires your assistance to develop an algorithm. You can assume
that the durations are read one at a time and should only be read until EOF (end of file) is
reached.
i. ] *Develop a flowchart to show your algorithm, using the diagrammatic
conventions described in the lecture.
s] What is the likely complexity of your program using big-O notation?

11.
Clearly point out what the primary parameters are and define your terms.
