You had learnt how to create the Pascal Triangle using recursion.
def pascal(row, col):
if col == 1 or col == row:
return 1
else:
return pascal(row - 1, col) + pascal(row - 1, col - 1)
But there is a limitation on the number of recursive calls. The reason is that the running time for recursive Pascal Triangle is exponential. If the input is huge, your computer won't be able to handle. But we know values in previous rows and columns can be cached and reused. Now with the knowledge of Dynamic Programming, write a function faster_pascal(row, col). The function should take in an integer row and an integer col, and return the value in (row, col).
Note: row and col starts from 1.
Test Cases:
faster_pascal(3, 2) 2
faster_pascal(4, 3) 3
faster_pascal(100, 45) 27651812046361280818524266832
faster_pascal(500, 3) 124251
faster_pascal(1, 1) 1
def faster_pascal(row, col):
if (row == 0 or col == 0) or (row < col):
return 0
arr = [[0 for i in range(row+1)] for j in range(col+1)]
arr[0][0] = 1
for i in range(1, row+1):
for j in range(1, col+1):
if i == j or j == 0:
arr[i][j] = 1
else:
arr[i][j] = arr[i-1][j] + arr[i-1][j-1]
return arr[row][col]

Code practice
Write a program that will ask a user how many numbers they would like to check. Then, using a for loop, prompt the user for a number, and output if that number is divisible by 3 or not. Continue doing this as many times as the user indicated. Once the loop ends, output how many numbers entered were divisible by 3 and how many were not divisible by 3.
Sample Run :
How many numbers do you need to check? 5
Enter number: 20
20 is not divisible by 3.
Enter number: 33
33 is divisible by 3.
Enter number: 4
4 is not divisible by 3.
Enter number: 60
60 is divisible by 3.
Enter number: 8
8 is not divisible by 3.
You entered 2 number(s) that are divisible by 3.
You entered 3 number(s) that are not divisible by 3.
Answer:
n = int(input("How many numbers would you like to check? "))
divisible_count = 0
not_divisible_count = 0
for i in range(n):
num = int(input("Enter a number: "))
if num % 3 == 0:
print(str(num) + " is divisible by 3")
divisible_count += 1
else:
print(str(num) + " is not divisible by 3")
not_divisible_count += 1
print("You checked " + str(n) + " numbers.")
print("Of those, " + str(divisible_count) + " were divisible by 3.")
print("And " + str(not_divisible_count) + " were not divisible by 3.")
Explanation:
You would run the program, it will ask the user to enter a number of integers, to check after that it will ask to enter numbers one by one, for each input, it will check if it's divisible by 3 or not, and keep counting how many were divisible or not divisible. After the loop ends, the program will output a summary of the total numbers checked, how many of them were divisible by 3 and how many were not.

Write a program that will ask the user to enter the amount of a purchase. The program should then compute the state and county sales tax. Assume the state sales tax is 5 percent and the county sales tax is 2.5 percent.in python
Answer:
This program first prompts the user to enter the amount of the purchase. It then defines the state and county sales tax rates as constants. It calculates the state and county sales tax amounts by multiplying the purchase amount by the appropriate tax rate. Finally, it calculates the total sales tax by adding the state and county sales tax amounts together, and prints the results.

Explanation:
Write a program that will calculate the internal angle of an n-sided polygon from a triangle up
to a dodecagon. The output to the console should show what the random number chosen was
and the value of the internal angle. Remember to find the internal angle of a polygon use:
360°
n
The program that will calculate the internal angle of an n-sided polygon from a triangle upto a dodecagon is given below
import random
def internal_angle(n):
angle = 360 / n
return angle
n = random.randint(3, 12)
print("Random number chosen:", n)
angle = internal_angle(n)
print("Internal angle of a", n, "-sided polygon:", angle, "degrees")
What is the Python program about?The program uses the formula for calculating the internal angle of a polygon, which is 360° divided by the number of sides (n). It also generates a random number between 3 and 12 to represent the number of sides of the polygon, and uses this value to calculate the internal angle.
The program starts by importing the random library, which is used to generate a random number. Then, it defines a function called "internal_angle" that takes one parameter, "n", which represents the number of sides of the polygon.
Inside the function, the internal angle of the polygon is calculated by dividing 360 by n and storing the result in the variable "angle". The function then returns this value.
Therefore, It's important to note that the internal angle of a polygon would be correct as long as the number of sides is greater than 2.

Start with a population of 500 organisms, a growth rate of 2, and a growth period to achieve this rate of 6 hours. Assuming that none of the organisms die, this would imply that this population would double in size every 6 hours. Thus, after allowing 6 hours for growth, we would have 1000 organisms, and after 12 hours, we would have 2000 organisms.
Write a program that takes these inputs and displays a prediction of the total population.
MY PROGRAM:
organisms=int(input("Enter the initial number of organisms:"))
growth=float(input("Enter the rate of growth [a real number > 1]:"))
numHours=int(input("Enter the number of hours to achieve the rate of growth:"))
totalHours=int(input("Enter the total hours of growth:"))
population = organisms
hours=1
while numHours < totalHours:
population *= growth
hours += numHours
if hours >= totalHours:
break
print(" The total population is ", population)
My program gives the correct answer for the original problems numbers, but when I run it through our test case checker it comes back as 3/4 correct.. the problem test case being [organisms 7, growth rate 7, growth period 7, total hours 7]... can't see where I'm going wrong...
Answer:
It looks like there are a few issues with your program.
First, the line hours += numHours should be hours += 1. This is because you want to increment the hours variable by 1 each time through the loop, not by the number of hours required to achieve the growth rate.
Second, you are only multiplying the population by the growth rate once per iteration of the loop, but you should be doing it every time hours is less than or equal to totalHours. You can fix this by moving the population *= growth line inside the loop's if statement, like this:
while numHours < totalHours:
if hours <= totalHours:
population *= growth
hours += 1
if hours >= totalHours:
break
Finally, you are using the variable numHours in your while loop condition, but it should be hours. You should change while numHours < totalHours: to while hours < totalHours:.
With these changes, your program should work correctly for the test case you provided. Here is the modified version of your program:
organisms=int(input("Enter the initial number of organisms:"))
growth=float(input("Enter the rate of growth [a real number > 1]:"))
numHours=int(input("Enter the number of hours to achieve the rate of growth:"))
totalHours=int(input("Enter the total hours of growth:"))
population = organisms

Answer:
The degree of a table refers to the number of attributes (columns) it has. In the case you described, after the 3 new attributes are added, the degree of the table would be 7 + 3 = 10.
The cardinality of a table refers to the number of rows (tuples) it has. In the case you described, after 2 tuples are deleted, the cardinality of the table would be 5 - 2 = 3. After 5 new students are added, the cardinality would increase to 3 + 5 = 8.
