Question

For this program you are given a String that represents stock prices for a particular company over a period of time. For example, you may be given a String that looks like the following:

String stockPrices = "1,22,30,38,44,68,49,73,52,66";
Each number in this String represents the stock price for a particular day. The first number is day 0, the second number is day 1, and so on. You can always assume tha the supplied string will formatted using commas to separate daily stock prices. The individual stock prices will always be valid integers, but they many not always be the same number of digits (i.e. 1 is a valid stock price, as is 1000. Your program should work with strings of any length. The "split" method might come in handy for this problem. Your task is to analyze the supplied string and determine the following:
• The highest price for the stock
• The day when the highest price occurred
• The lowest price for the stock
• The day when the lowest price occurred
Here are two sample runnings of the program:
// First run
Please enter stock prices: 1,22,30,38,44,68,49,73, 52,66
Highest price: 73 ocurred on day # 7
Lowest price: 1 occurred on day # 0
// pecond run
Please enter stock prices: stock_prices - 41,37,40,54,51,63,54,47,23,33
Highest price: 63 occurred on day # 5
Lowest price: 23 accurred on day # 8
Write your program on the following page. You can use this page for rough work.

Answer 1

price = input("Please enter stock prices: ")

x = price.split(",")

min = int(x[0])

max = int(x[0])

for i in x:

if int(i) < min:

min=int(i)

if int(i) > max:

max=int(i)

index = x.index(str(max))

print("Highest price: "+str(max)+" ocurred on day # "+str(index))

index = x.index(str(min))

print("Lowest price: "+str(min)+" ocurred on day # "+str(index))

Step-by-step explanation:

This solution is implemented in Python

This prompts user for stock prices

price = input("Please enter stock prices: ")

This places the price in a list

x = price.split(",")

The next two lines initialize the lowest and highest to stock at index 0

min = int(x[0])

max = int(x[0])

This iterates through the list

for i in x:

The following if statement checks for the lowest

if int(i) < min:

min=int(i)

The following if statement checks for the highest

if int(i) > max:

max=int(i)

This gets the day for the highest stock

index = x.index(str(max))

This prints the highest price and the day it occurred

print("Highest price: "+str(max)+" ocurred on day # "+str(index))

This gets the day for the lowest stock

index = x.index(str(min))

This prints the lowest price and the day it occurred

print("Lowest price: "+str(min)+" ocurred on day # "+str(index))
