ANDROUND - AND Rounds |
You are given a cyclic array A having N numbers. In an AND round, each element of the array A is replaced by the bitwise AND of itself, the previous element, and the next element in the array. All operations take place simultaneously. Can you calculate A after K such AND rounds ?
Input
The first line contains the number of test cases T (T <= 50).
There follow 2T lines, 2 per test case. The first line contains two space separated integers N (3 <= N <= 20000) and K (1 <= K <= 1000000000). The next line contains N space separated integers Ai (0 <= Ai <= 1000000000), which are the initial values of the elements in array A.
Output
Output T lines, one per test case. For each test case, output a space separated list of N integers, specifying the contents of array A after K AND rounds.
Example
Sample Input: 2 3 1 1 2 3 5 100 1 11 111 1111 11111 Sample Output: 0 0 0 1 1 1 1 1

2 questions say if new A[0] is calculated , then for calculating A[1] , the A[0] used is the newly calculated or previous one ? A follow up question is if its the new one then wont it be important to know from where does the ANDing round start ? @Xilinx : My bad !! Thanks , not removing my question just in case it might help some one else !! Last edit: 2010-01-11 06:14:34 |
