Let the sequence A[], B[] and C[] be a non-decreasing sequence and have N, M, and K elements, respectively. Your service is find the common elements of these 3 numbers
input:
- First line is test the number of T (T<20)
- Each test consists of integers N, M and K (1≤ N, M, K ≤ 100 000).
- The next line consists of N integers A[i], then M integers B[i] and K integers C[i].(0 <= A[i], B[i], C[i] <= 10^9)
output :
- For each test, print on one line the answers obtained. If you can’t find the answer, print “NO”
Input :
