Guys if any one can help me to solve this by type a code please:

Question

No one likes homework, but your math teacher has given you an assignment to find the sum of the first N numbers.

Let’s save some time by creating a program to do the calculation for you!

Take a number N as input and output the sum of all numbers from 1 to N (including N).

Sample Input
100

Sample Output
5050

Explanation: The sum of all numbers from 1 to 100 is equal to 5050.

Answer 1

the sum of all numbers from 1 to 100 is actually 4950, not 5050. 5050 if you add 100 to it.

the sum from 1 to 100 = 4950
4950 + 100 = 5050

so you need to loop from 1 to 100 to get 4950, then after the loop add 100 to get 5050

Answer 2

s=0
for i in range(1,int(input())+1):
s=s+i
print(s)
