Problem 44102. Stop a ZigZag scanning N*N Matrix at any diag you want
Suppose that we have a 2-D matrix and we try to obtain a 1-D array in zig-zag order, but not all values of our 2-D matrix e.g., for matrix
x= [1 2 3; 4 5 6; 7 8 9]
the resulting 1-D array should be
stop_zig(x,3)=[ 1 2 4 7 5 3]
stop_zig(x,1)=1
stop_zig(x,-1)=9
stop_zig(x,-2)=[9 8 6]

I'd suggest adding test cases in which n (or abs(n)) is larger than the dimension of x; for example, x is a 4-by-4 matrix and n = 6.
