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
Input: 2 3 1 1 2 3 5 100 1 11 111 1111 11111 Output: 0 0 0 1 1 1 1 1

Use scanf and printf or fast I/O, else you will get TLE. |

b is equal to ( b& INT_MAX). |

n = 20000 worked for me. |

The value of N seems to be greater than 20000 . N = 22000 worked fine for me. Last edit: 2013-05-14 06:13:12 |

seems that n > 20000 in test files ... |
