binary search if of order log n where as sequential search
is of order n
binary search is faster..

Answer / nishant singh
Binary search is faster because we traverse the elements by
using the policy of Divide and Conquer.
we compare the key element with the approximately center
element, if it is smaller than it search is applied in the
smaller elements only otherwise the search is applied in the
larger set of elements.
its complexity is as we all know is log n as compared to the
sequential one whose complexity is n.

Answer / ahan
The binary search is faster than the sequential search.The
complexity of binary search is 'log n' where as the
complexity of sequential search is 'n'.Since each time we
are proceeding we have to deal with only half of the
elements of the array than the previous one.So we can easily
get a number from an array of elements through binary search
than sequential search.

Answer / naresh
binary search..if the elements are not in a sorted order
then sequential search or linear search would be better.

Answer / ujjwal dave
binary search is faster and more useful in case we need to
perform search a number of times, complexity of sequential
search will be n each time where in binary search will take
more time only at first time when data is not sorted once
the data is sorted......it will take only only log n
attempts to search each element.......so the decision also
depends on frequency of the data beign searched
