Distinguish between write through and write back.

Assume a fully associative write back cache with many cache entries that starts empty. Below is a sequence of memory operations $($the address is in square brackets$).$

I. Readmem $[500]$

II$.$ WriteMem $[500]$

III. ReadMem $[400]$

IV$.$ WriteMem $[300]$

V$.$ ReadMem $[200]$

VI$.$ ReadMem $[400]$

VII. ReadMem $[300]$

VIII. WriteMem $[300]$

IX$.$ WriteMem $[200]$

X$.$ ReadMem $[300]$

XI$.$ WriteMem $[300]$

What are the numbers of hits and misses when using no$-$write allocate versus write allocate scheme?
