Programming Assignment  

Q1. Take an input N as an integer and write a program to display a right angle triangle with N rows and          N columns .

INPUT    5

OUTPUT 

                *

                *  * 

                *  *  *

                *  *  *  *

                *  *  *  *  * 

CODE: 

 N = int(input())

 for i in range(1,N+1):

       for j in range(1,i+1):

             print('* ',end="")

       print(){codeBox}

Q2. Write a program to take an input N and print Fibonacci sequence till N terms.

The Fibonacci sequence is a set of integers (the Fibonacci numbers) that starts with a zero, followed by a one, then by another one, and then by a series of steadily increasing numbers. The sequence follows the rule that each number is equal to the sum of the preceding two numbers.  

INPUT  7 

OUTPUT    0 

                    1

                    1

                    2

                    3

                    5 

                    8

Explanation: since the input is 7 there are seven terms. The first two terms are always 0 and 1. The third term is sum of first two terms. The fourth term is sum of second and third terms and so on.

CODE:  

N=int(input())

L=[0,1]

if N==1:

  print(0)

elif N==2:

  print(0)

  print(1)

else:  

  print(0)

  print(1)

  for i in range(N-2):

    if i==N-3:

      print(L[-1]+L[-2],end="")

    else:

      print(L[-1]+L[-2])

    L.append(L[-1]+L[-2]){codeBox}

         

Q3. Take Base B and height H as an input and write a program to print a parallelogram 

INPUT    8

                4

OUTPUT 

           

               ********

               ********

               ********

               ********

CODE:  

B=int(input())

H=int(input())

for i in range(H):

  for j in range(B):

    print('*',end="")

  if i!=H-1:  

    print() {codeBox}
