Estimate:Mid
Explanation:This region has a similar structure to Example 1.
The innermost loops (on lines 4 & 10) are the most frequently repeated array references. Out of the 2 accesses on line 4, the first accesses consecutive memory locations while the second accesses locations that are at least 'size' locations apart.
A similar estimation can be made for the loop on line 10.
Therefore, only 1 out of every 2 array accesses has a local stride of 1.
