write a cobol program using ACCEPT verb to take values from terminal like hackerrank or any online tool, read array size and binary values.

calculate how many minimum steps need to swap values so that all zero one side and all ones one side, any side is fine.

For example:$-$

Array size and values

$4$

$0$

$1$

$0$

$1$

output :$-1$

sample $2$

$6-$ array size

$1$

$1$

$0$

$0$

$0$

$1$

output:$3$

sample test case$3$

$4$

$1$

$1$

$0$

$0$

output $0$ because already in aligned order.

sample test case $4$

$5$

$1$

$0$

$1$

$0$

$1$

output $3$

write cobol program test it throughly for $6$ to $8$ different test cases and I need to test in hackerank.
