Consider the following code: for i= m to n increment 2 { print "Hello!" }

Consider the following code:

for i= m to n increment 2

{ print "Hello!" }

Assuming m < n and exactly one of (m,n) is even, how many times will Hello be printed?

Option 1 : (n - m + 1)/2

Option 2 : 1 + (n - m)/2

Option 3 : 1 + (n - m)/2 if m is even, (n - m + 1)/2 if m is odd

Option 4 : (n - m + 1)/2 if m is even, 1 + (n - m)/2 if m is odd

Answer: Option 1
