How do I implementing additional branch coverage to partial test case in 4 partition in bash script

I whave 13.545 file. i want to count the sum of digit 1 in that file but first we must compare 2 file that we select randomly from that file. Here the example

BranCov1 (file1)= 1 0 1 1 1 0
BranCov2 (file2)= 1 1 1 1 0 0

Result(in file)= 1 1 1 1 1 1 **Count**=5

After that we select one file randmly again and compare it with the Result. This proces looping after the Count is 1014. How can i do that with bash script?
