Question 2:
Give an algorithm to calculate the sum of first n numbers. For
example, if n = 5, then the ouput should be 1 + 2 + 3 + 4 + 5 = 15.
Give three solutions for this problem. The first solution with a
complexity O(1), the second solution with a complexity O(n), and
the third solution with a complexity O(n2).
Solution 1:
Solution 2:

Question 3:
Given this algorithm:
i=1;
sum
=
0;
while
(i < m)
{
j=n;
while
(j > n/2)
{
print(i,j)
j
= j - 1;
}
i
= i
+1;
