HOW TO ANSWER IN PYTHON :

PROBLEM: Given a positive integer (call it ​N), a position​ ​in that integer (call it ​P), and a transition integer (call it ​D). Transform ​N as follows:
If the ​Pth​ digit of ​N from the right is from​ ​0 to 4, add ​D to it. Replace the ​Pth​ digit by the units digit of the sum. Then, replace all digits to the right of the ​Pth​ digit by 0.
If the ​Pth​ digit of ​N from the right is from​ ​5 to 9, subtract ​D from it. Replace the ​Pth​ digit by the leftmost digit of the absolute value of the difference. Then, replace all digits to the right of the ​Pth​ digit by 0.
nd​
Example 1: N = 7145032, P = 2, D = 8 . The 2​ digit from the right is 3; add 8 to it (3+8=11),
and replace the 3 with 1 to get 7145012. Replace the digits to the right by 0s to get 7145010. rd​
Example 2: N = 1540670, P = 3, D = 54 . The 3​ digit from the right is 6; the absolute value of 6-54 is 48; replace with the 4 to get 1540470. Replace the digits to the right with 0s to get 1540400.
INPUT: There will be 5 sets of data. Each set contains 3 positive integers: ​N, P, and ​D. N will be less than 1015 ; ​P and​ D will be valid inputs. No input will cause an output to have a leading digit of 0.
OUTPUT: Print the transformed number. The printed number may not have any spaces between the digits.

ANSWER:

N=input("Enter a positive integer(N):")   
P=int(input("Enter position(P):"))
D=int(input("Enter transition integer(D):"))
int_N=int(N)
ele=int(N[len(N)-P]) #for element at postion P form right
if(ele>=0 and ele<=4):
D=D+ele #if element <4 D is added
D=str(D)
t_num=N[0:len(N)-P]+D[len(D)-1] #adding number till position with unit digit from D added with element
n_z=len(N)-len(t_num)
t_num=t_num+'0'*n_z #adding zeros to right of number
  
else:
D=abs(D-ele) #if element >4 D is subtracted
D=str(D)
t_num=N[0:len(N)-P]+D[0] #adding left most digit from D after subtracting from element
n_z=len(N)-len(t_num)
t_num=t_num+'0'*n_z

print("Transformed number is:",t_num)

In Python, write a program to get a positive integer n from keyboard first (your program must be able to check the validation of n being positive), and then get n integers from keyboard and store these n integers in a list. Do some processing, and print out average of the elements in the list at end of your program. For example, suppose user enters 3 first (n = 3), which means we get another three integers from the user....

Given a list of positive integers c[0...n − 1], and a positive integer v, decides whether we can use numbers from c[0...n − 1] to make a sum of v, allowing any particular number in the list to be used multiple times. Or, mathematically, this means that there exists non-negative integer coefficients, x0, x1, ..., xn−1, such that v = x0c[0] + x1c[1] + ...xn−1c[n − 1]. For example, given c[0...3] = {2, 4, 6, 10}, and v = 17,...

IN PYTHON Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x // 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string....
