Question_1:-
Using the method of looping, write a program to print the table of 9 till N in the format as follows:
(N is input by the user)

9 18 27...

Print NULL if 0 is input
Sample Input :
3
Sample Output :
9 18 27
******************
N = int(input())
arr = []
for i in range(1,N+1):
print(*arr)
_________________
Question_2:-
Write a code to get an integer N and print the sum of values from 1 to N.
Sample Input :
10
Sample Output :
55
*****************
a = int(input())
k = 0
for i in range(1,a+1):
k += I
print(k)
_________________
Question_3:-
Write a code to get 2 integers A and N. Print the integer A, N times in separate line.
*****************
A, N = map(int,input().split())
for i in range(N):
print(A)

Question_4:-
You are provided with the radius of a circle "A". Find the length of its circumference.
Sample Input :
2
Sample Output :
12.57
******************
A = float(input())
C = 2*(22*A)
D = C/7
print(round(D,2))
_________________
Question_5:-
Write a code get an integer number as input and print the sum of the digits.
******************
n = int(input())
r = 0
while n 'use grater than sign' 0:
d = n%10
r = r+d
n = n//10
print(r)
_________________
Question_6:-

******************
a = input()
print(a[::-1])
_________________
Question_9:-
Write a code to get an integer N and print the even values from 1 till N in a separate line.
******************
num = int(input())
for i in range(1, num+1):
if i % 2 == 0:
print(i)
_________________
Question_10:-
Write a code to get an integer N and print values from 1 till N in a separate line.
******************
num = int(input())
for i in range(1, num+1):
print(i)
_________________
Question_11:-
Print the First 3 multiples of the given number "N". (N is a positive integer)

Note: print the characters with a single space between them.
******************
N = int(input())
print(N,N*2,N*3)
_________________
Question_12:-
You are given with Principle amount($), Interest Rate(%) and Time (years) in that order. Find Simple Interest.
Print the output up to two decimal places (Round-off if necessary).
(S.I. = P*T*R/100)
******************
P,T,R = map(float,input().split(' '))
A = P*T*R
B = A/100
print(round(B,2))
_________________
Question_13:-
You are provided with two numbers. Find and print the smaller number.
Input Description:
You are provided with two numbers as input.

Output Description:
Print the small number out of the two numbers.

Sample Input :
23 1
Sample Output :
1
*****************
arr = list(map(int,input().split()))
print(min(arr))

Please make video on Segment Tree to this question please
Jack is playing with an array A of N numbers. Each number in the array is either 0 or 1
Replacing a 0 with 1 costs X rupees.
Replacing a 1 with 0 costs Y rupees.
Jack is given Q queries of the form L R where he wants to know what is the minimum cost to make the subarray A[L], A[L+1], A[L+2] …. A[R] such that all elements are 0 or all elements are 1. Help him solve this problem.


Input Description:
The first line contains a single integer N representing the size of the array The second line contains N integers each of which is 0 or 1 The third line contains a single integer Q - the number of questions The next Q lines consist of a four integers L R X Y each representing the query for range L, R and the cost of replacement for that query

Output Description:
The output must consist of Q lines each of which contains a single integer-the answer to the corresponding query.

Sample Input :
4
1 0 1 1
1
1 4 10 0
Sample Output :
0

😅😅😅😅😅😭😭😭😭😭😭😭😭😭😭I wants only 1 question even and odd on separate line now but it is not there!

[sakthivel.]

A, B = map(int, input().split())
EOFError: EOF when reading a line i am getting this error . How do solve this.
