Question

HELP! HOW WOULD I WRITE THIS IN PSEUDOCODE?

from itertools import accumulate
from collections import Counter

def addvalues(a, b):
if type(a) is str:
a = a.strip("\n")
if type(b) is str:
b = b.strip("\n")
return int(a) + int(b)

def maxValues(a, b):
if type(a) is str:
a = a.strip("\n")
if type(b) is str:
b = b.strip("\n")
a = int(a)
b = int(b)
return max(a, b)

def main():
counter = 0
total = 0
maximum_cars = 0
file = open("MainAndState.dat", "r")
maximum = accumulate(file, maxValues)
for maximum_cars in maximum
pass
file.seek(0)
result = accumulate(file, addvalues)
for total in result:
counter+=1
print("Maximum number of cars observed per day: {}".format(maximum_cars))
print("Total Cars: {}".format(total))
print("Total days observed: {}".format(counter))
print("Average number of cars observed per day: {}".format(total/counter))

file.close()
  

if __name__ == "__main__":
main()

PSEUDO-CODE:

1. DEFINE FUNCITON addvalues(a,b)
   (i) Check if a is of string type:
           if so strip it from the rest of line i.e '\n character.' and store it in a.
   (ii) check if b is of string type:
           if so strip it from the rest of line i.e '\n character.' and store it in a.
   (iii) return a + b after casting them in to integers by using int() function.

2. Define Function maxValues(a,b)
   (i) Check if a is of string type:
           if so strip it from the rest of line i.e '\n character.' and store it in a.
   (ii) check if b is of string type:
           if so strip it from the rest of line i.e '\n character.' and store it in a.
   (iii) return max(a,b) after casting them in to integers by using int() function.
   #see you haven't defined logic for returning max (a,b) i.e if a>b:
   return a;
   else: return b;
3. Define main() function in which actual process is written:
   (i) initialize counter, max, maximum_cars with 0.
   (ii) Open file "MainAndState.dat" in read mode.
   (iii) assign iterator accumulate of file by passing file and function maxValues as its object to find max of every line in the file.
   (iv) now iterating he maximum values we add values the variable result using accumulate iterating by passing file and fucntion object addValues as parameter.
   (v) update the counter at every iteration. and go to next element in maximum list i.e step iv.
   (vi) print maximum_cars,total,counter,and average = total /counter to the output each in newLine.
   (vii) close the opened file in step (ii).
4. call main() in __main__ system call.
