Cache Access Question Miss-Hit specify if there is hit or miss according to first given table to address values in the second one

A processor has a data cache which has 8 cache-lines as in the following figure.

Index	Valid	Tag	Data
000	Y	11	XXXXXXX
001	Y	10	XXXXXXX
010	N
011	N
100	Y	00	XXXXXXX
101	Y	01	XXXXXXX
110	N
111	N

a) Following addresses come to the cache in the given order. Write down which of them are hit and which of them are miss?

Address(decimal)	Binary	Hit/Miss
21
11
19
16
3
6
4
31
4
31
