Untitled - Notepad File Edit Format View Help Algorithms 1.You have been given a 1le with two columns: a name and an integer (whole number representing how many aquatics training sessions the person has attended in semester 1 between 0 and 24 inclusive. The 1le will look something like: Ada 22 Jordan 10 Anita 15 Xavier 24 are in the 1le, however the 1le will be terminated by It is not known at the outset how many rows EOF (end of 1le) a) [5 marks] Draw a 2owchart (following the conventions used in class) that reads the 1le and then calculates and prints the number of club members who attended less than 5 sessions. b) [12 marks] What is the likely complexity of your program using big-0 notation? Clearly point out what the primary parameters are and delne your terms. 3. [3 marks] Given the sequence calculated by seq(n) seq(n B 1) 8.1, write a recursive function to calculate the solution given n as input. Assume n is positive and that seq(e) 1.

Answer 1

Data which i have used for this experiment::-

sachin 12

kumar 13

sam 05

Anita 04

Ada 03

Xavier 10

Source Code::-

fp = open("data.txt", "r")

#Opening the file where data is stored

count = 0 #count variable which count no of member who attended less than 5 sessions.

for f in fp:

   #Looping one by one line from the file

   session = f.split()[1]

   #storing no of session people has attended

   if int(session) < 5:

#If session is less than 5 then increment the count by one

count +=1

print("%s Club Member Who has attended less than 5 sessions::" %count)

Output::-

2 Club Member Who has attended less than 5 sessions::

p -open ("data.txt", "r") #Opening the file where data is stored count #count variable which count no of member who attended less than 5 sessions. for f in fp: #Looping one by one line from the file session = f.split()[1] #storing no of session people has attended if int(session) < 5 #lf session is less than 5 then increment the count by one count +1 print("%s Club Member who has attended less than 5 sessions." %count)

Output Screen Shot::-

2 Club Member Who has attended less than 5 sessions:

(b)Solution::-

Complexity of the source code is n.I have used one loop inside the program and It will loop one by one item

so it will go 1 to n.

complexity is n.
