# Preliminary notes: 
- Presumed knowledge 
- Use only the studied material 


# (1) Write a program that receives non-negative 
#     integers one after another. 
#     The iteration stops when the number -1 is entered. 
#     The program calculates how many integers 
#     are smaller than 100, and prints the result. 
    
# 1
num = int(input("PLease enter a non-negative integer: "))
counter = 0 
while num != -1:
    if num < 100: 
        counter = counter + 1 
    print(counter)
    num = int(input("PLease enter a non-negative integer: "))
print("Number of integers smaller than 100:", counter)



# 2 
while True: 
    num = int(input("PLease enter a non-negative integer: "))
    if num == -1: 
        STOP THE LOOP 
    else: 
        print("bamba")
    
    
    
# (2) Write a program that receives a non-empty string s
#     and then a series of additional non-empty strings. 
#     The iteration ends when an empty string is entered. 
#     The program prints the number of strings 
#     other than s that are equal to s. 

s = input("Please input any string: ")
otherS = input("Please input another string: ")
counter = 0 
while otherS != "": 
    if s == otherS: 
        counter = counter + 1
    otherS = input("Please input another string: ")
print("Number of strings equal to first string: ", counter)
        
        
     

# (3) Two chefs have made it to the final 
#     round of the international chefs 
#     championship. The audience chooses 
#     the winner. Write a program that 
#     receives the votes, either 1 for 
#     the first chef, or 2 for the second. 
#     The iteration ends when 0 is entered. 
#     The program prints the number 
#     representing the winner. 

vote = input("Please enter your vote, 1 or 2: ")
counter1 = 0
counter2 = 0

if counter1 > counter2: 
    print(1)
elif counter2 > counter1: 
    print(2)

    print("TIE") 



# (4) The newspaper "Read Me" has a gift 
#     for new subscribers: either a book 
#     for those over 50 year old, 
#     or a movie ticket for all other 
#     subscribers. Write a program that 
#     receives the ages of new subscribers. 
#     The iteration ends when the number -1 
#     is entered. The program prints for each 
#     subscriber her/his gift: "book" or "movie". 
#     The program also prints the number 
#     of subscribers who were given books 
#     and the number of those who were 
#     given movie tickets. 

age = int(input("Please enter age: "))
over50 = 0 
notOver50 = 0 
while age != -1: 
    if age > 50:

        notOver50 = notOver50 + 1    
    age = int(input("Please enter age: "))
print("Number of books:", over50)
print("Number of tickets:", notOver50)
    
    
    
# (5) Write a program that receives 
#     non-negative integers one after another. 
#     The iteration ends when the number -1 
#     is entered. The program calculates 
#     the sum of odd integers, and prints 
#     the result. 
    
num = int(input("Please enter a non-negative integer: "))
sumNums = 0 
while num != -1: 
    if num % 2 == 1: 
        sumNums = sumNums + num 
    num = int(input("Please enter a non-negative integer: "))

# (6) Write a program that receives a number
#     greater than 50 and finds how many 
#     integers whose ones digit is 5 sum up to 
#     a number smaller than the received number. 
#     The program prints the calculated sum 
#     and the number of integers. 
51 
5 + 15 + 25

sumNums = 0 
intEndingWith5 = 5

    counter = counter + 1 
    print(counter, intEndingWith5, sumNums)
print("Number of integers:", counter)
print("Sum of integers:", sumNums)



# (7) Write a program that receives non-negative 
#     integers one after another. The iteration ends 
#     when -1 is entered. The program finds the 
#     average of integers greater than 5. 

num = int(input("Please enter a non-negative integer: "))
sumNums = 0 
counter = 0
while num != -1: 
    if num > 5: 
        counter = counter + 1 
        sumNums = sumNums + num         
    print(counter, sumNums)
    num = int(input("Please enter a non-negative integer: "))
print("Average is", sumNums / counter)



# (8) Write a program that receives 
#    non-negative integers one after another. 
#    The iteration ends when -1 is entered. 
#    The program finds the biggest even 
#    integer. 

num = int(input("please enter a non-negative integer: "))
maxNum = -1 
while num != -1: 
    if num % 2 == 0: 
        if num > maxNum: 
            maxNum = num 
    num = int(input("please enter a non-negative integer: "))
print("Maximal ever integer: ", maxNum)





# (9) Write a program that compares between 
#     the prices of two cottage brands in 
#     branches of a supermarket chain. 
#     The program iteratively receives pairs of 
#     brand prices in all branches. The iteration 
#     ends when the string 'q' is entered as 
#     the price of the first cottage in a pair. 
#     The program prints the number of branches 
#     in which the price of the first brand was 
#     bigger than the price of the second brand. 

price1 = input("Please enter brand 1 price: ")
counter = 0 
while price1 != 'q': 
    price1 = float(price1)
    price2 = float(input("Please enter brand 2 price: "))
    if price1 > price2: 
        counter = counter + 1 
    price1 = input("Please enter brand 1 price: ")
print("Number found: ", counter)

    if price1 > price2: 
        counter = counter + 1     
print("Number found: ", counter)        





# (10) Write a program that checks the efficiency 
#      of a doctor-s work in a certain day. 
#      The program iteratively receives 
#      for all patients checked by the doctor 
#      both their ids and the number of checkup 
#      minuets. This data is received in 
#      id-minutes pairs. The iteration ends when 
#      the string 'stop' is entered as the id. 
#      The program finds the patient whose checkup 
#      was the shortest (you may assume there was 
#      only one such patient), and prints her/his 
#      id and that number of minuets. 

# with continue 
proceed = True 
minMinuets = 60 * 24 
while proceed: 
    patientID = input("Please enter patient's id: ")
    if patientID == 'stop': 
        proceed = False 
        continue      
    minutes = int(input("Please enter number of minuets: "))

print(idMin, minMinuets)        




(11) Write a program that implements the 
   following dice game. In each round two cubes 
   whose faces display the numbers 1–6 are 
   rolled. Following each roll the sum of number 
   on the upper faces is calculated. 
   The game ends when in three consecutive 
   rolls the sum is 12. The program should 
   include the following line: 
   while (True) 
   When the program ends it prints the 
   number of tosses, not counting the last 
   three tosses.

4 5 
6 6   -> round = 1 
2 5 
6 6   -> round = 1
6 6   -> round = 2 
1 4   -> round = 0  
6 6   -> round = 1
6 6   -> round = 2 
6 6   -> round = 3 ---> break 

import random 
rounds = 0 
rolls = 0 
while True: 
    dice1 = random.randint(1, 6)
    dice2 = random.randint(1, 6)

    if dice1 + dice2 == 12: 
        rounds = rounds + 1 
        print(dice1, dice2, rounds)
        if rounds == 3: 
            break 
    else: 
        rounds = 0 
    print(dice1, dice2, rounds)
print("Number of rolls", rolls - 3)
