The Joy Of Computing Using Python Programming Exam Oct 2022 (Second Session): (8PM - 9PM)
Exam Problem 1
Question 1 : You are in charge of making blueprints of a high-security prison for superhumans. Your task is to take the number of rows and number of columns as input and design the blueprint for the construction.
Input: The first line contains the number of rows N and number of columns M of the prison.
Output: Blueprint of prison according to sample output.
Example:
Input: 3 4
Output:
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
|.|.|.|.|
+-+-+-+-+
x,y = map(int,input().split())
p = ['+' for i in range(y+1)]
q = ['|' for i in range(y+1)]
r = '-'.join(p)
s = '.'.join(q)
for j in range(x):
print(r)
print(s)
print(r,end = '')
Exam Problem 2
Question 2 : Given a list in which each element is a tuple containing (country, country_code). Write a function convertL that takes the list as an argument and returns a dictionary containing keys as country and values as country_code, arranged in ascending order with respect to country code.
Sample Input:
L = [(Sri Lanka, +94), (India, +91)]
Sample output:
{ ‘India’: ‘+91’, ‘Sri Lanka’: ‘+94’}
def convertL(L):
item = dict()
for i in sorted(L):
item[i[0]] = i[1]
myDict_values = sorted([int(i) for i in item.values()])
myDict = dict()
for i in myDict_values:
for j in item.keys():
if item[j] == "+"+str(i):
myDict[j] = item[j]
return(myDict)
n = int(input())
L = []
for i in range(n):
L.append(input().split())
print(convertL(L))
Programming Exam Oct 2022 (First Session): (10AM - 11AM)
Exam Problem 1
Question 1 : Ramesh is the principal of a school. Every year, he appoints some teachers to calculate the grades of students from the marks scored by them. Since technology is evolving Ramesh wants to digitize this process. So, he decided to hire a programmer for this task.
You are given a dictionary where the keys are the name, and the values are another dictionary that contains subjects as keys and marks as values. Write a function convertMarks that takes a dictionary as an argument and returns a dictionary with marks replaced with grades.
Example input:
{‘Lakshman’: {‘Maths’: 90, ‘English’: 75, ‘Social Science’: 10}
Example output:
{‘Lakshman’: {‘Maths’: B, ‘English’: C, ‘Social Science’: F}
def converMarks(num):
for pupil in d.keys():
for marks in d[pupil].keys():
m = d[pupil][marks]
if m>=91 and m<=100:
d[pupil][marks] = 'A'
elif m>=81 and m<=90:
d[pupil][marks] = 'B'
elif m>=71 and m<=80:
d[pupil][marks] = 'C'
elif m>=61 and m<=70:
d[pupil][marks] = 'D'
elif m>=51 and m<=60:
d[pupil][marks] = 'E+'
elif m>=41 and m<=50:
d[pupil][marks] = 'E'
elif m>=0 and m<=40:
d[pupil][marks] = 'F'
return(d)
name = input().split()
d = {}
for i in name:
d[i] = {}
subjects = input().split()
marks = input().split()
for j in range(len(subjects)):
d[i][subjects[j]] = int(marks[j])
print(converMarks(d))
Exam Problem 2
Question 2 : Shyam has N Jars of Ladoos and he wants to distribute the Ladoos amongst M Villagers. The i-th jar contains Li pieces of Ladoos. He wants to make sure that every villager gets the same amount of ladoos and that the number of ladoos they receive is the greatest possible. He can open each jar and mix all the ladoos before distributing them to the villagers. How many pieces of ladoos will remain after he shares them amongst villagers, based on the rules described above?
n,m=map(int,input().split())
l=[int(i) for i in input().split()]
s=0
for i in l:
s+=i
print(s%m,end='')
