probably the only entirey different approach ( except small variations in Bsearch ) is use of Hashing ( or for that matter , HashMaps ) On Sun, Oct 25, 2009 at 1:36 PM, harit agarwal agarwalha...@gmail.comwrote: the only other way can be the jump exponentially during search as in binary search

yeah i've solved it using binary search but i want to know more solutions On Oct 25, 10:59 am, Antony Vincent Pandian.S. sant...@gmail.com wrote: Do a binary search On Sun, Oct 25, 2009 at 12:13 AM, naren lalavat38na...@gmail.com wrote: You have a sorted array of n elements some of them

the only other way can be the jump exponentially during search as in binary search a[mid] is checked so if a[mid]!=x then make low=highest index of a[mid]!=x this will reduce the comparisionsin binary search ex-1,1,1,2,2,2,3,3,3,4,4,5,5(13 elements) let's search for 4 modify binary search
