[algogeeks] Re: Finding the repeated element

2012-07-23 Thread Rahul Kumar

what is the time complexity for the code ?

#includeiostream
using namespace std;

main()
{
int arr[] = { 2,3,4,9,2,7};
int *ptr1 = arr[0];
int *ptr2 = arr[1];
const int SIZE = sizeof arr / sizeof arr[0];
while(1)
{
if(*ptr1 == *ptr2)
{
cout  *ptr1  endl;
return 0;
}
if( ptr1 == (arr+SIZE*(sizeof arr[0])))
ptr1=arr;
else
ptr1++;
if( ptr2 == arr[SIZE-2])
ptr2=arr+1;
else if( ptr2 == arr[SIZE-1])
ptr2=arr;
else 
ptr2+=2;
} 
return 1;
}

Re: [algogeeks] Re: Finding the repeated element

2012-07-23 Thread Dave
@Arun: The referenced algorithm solves the wrong problem. The problem given 
has n-2 unique elements and 1 element repeated twice. The referenced 
algorithm has n-1 elements that occur in pairs and one that is unique; 
xoring will solve this problem, but it won't help solve the given one.
