Question
In a competition, four different functions are observed. All the functions use a single
for loop and within the for loop, same set of statements are executed. Consider the
following for loops:
a) for (i = 0; i<n; i++)
b) for (i = 0; i<n; i+= 2)
c) for (i = 1; i<n; i *= 2)
d) for (i = n; i>-1; i/= 2)

2 logn
If n is the size of input (positive), which function is most efficient (if the task to be
performed is not an issue)?
