For the first question, if input array A[4][4] is:
1 2 4 7
3 5 6 10
8 9 11 14
12 13 15 0
This array also obeys the basic condition A[i][j] <A[i+1][j] and A[i][j]<A[i][j+1] , for all i,j€[1,2,3]. But A[4][4] may contain the minimum value. So how we can confirm that A[1][1] will contain the minimum value.
