I have one more approach in mind where it requires T(n) = O(n) and O(1) space complexity. here it goes: 1) Start traversing the array. 2)Store the location when 0 and 1 both appears for the first time in some variable. 3)Similarly store the location of 0 and 1 when both appears for the last time

@sunny: if a[i]==0 then 0,i is the solution suppose a[i]==a[j] ==0 now 0,i and 0,j is the solution. is i,j also the solution?? On Jul 1, 4:08 pm, sunny agrawal sunny816.i...@gmail.com wrote: String = 1 0 1 1 0 1 1 1. 1. make the  array = 1 -1 1 1 -1 1 1 1 2. after second operation array = 1 0

yes but for largest interval we need only one index :) greater of i or j On Fri, Jul 1, 2011 at 6:01 PM, Dumanshu duman...@gmail.com wrote: @sunny: if a[i]==0 then 0,i is the solution suppose a[i]==a[j] ==0 now 0,i and 0,j is the solution. is i,j also the solution?? On Jul 1, 4:08 pm, sunny
