A	B	C	D	E	Result
1	1	1	0	0	C
1	0	0	1	0	D
0	0	1	0	1	E
0	1	0	1	0	D

Like in the table above. I want to lookup the value in each row and return the header name which is the most right number "1" is located.
I know that we should use the index and match but I am not sure how to find "position of the most right number 1 located"
