Given an array of length N containing integers between 1
and N, determine if it contains any duplicates.
Answer Posted / sid
duplicate = False;
for (i =1; i <= N; i++)
{
a[a[i] % N] += N;
}
for (i =1; i <= N; i++)
{
if (a[i] / N >= 2)
{
duplicate = True;
}
}
return duplicate;

You have given 2 array. You need to find whether they will
create the same BST or not.
For example:
Array1:10 5 20 15 30
Array2:10 20 15 30 5
Result: True
Array1:10 5 20 15 30
Array2:10 15 20 30 5
Result: False
One Approach is Pretty Clear by creating BST O(nlogn) then
checking two tree for identical O(N) overall O(nlogn) ..we
need there exist O(N) Time & O(1) Space also without extra
space .Algorithm ??

//n1 size of array a1[] and n2 size of a2[]
if(n1!=n2) return false;
//n1 and n2 must be same
