Merge of Logical Indexing one dimension matrix from multi dimension?

A = [

0 0 0 0 0 0 0 1 1 1 1 1 1 1 0 0 1 0 0 0 1 1 1 0 0 ;

0 0 0 1 1 0 0 1 1 1 1 0 1 1 0 0 0 1 0 0 1 0 1 0 0 ;

0 0 0 0 0 0 0 1 1 1 1 1 1 1 0 0 0 0 0 0 1 1 1 0 0 ;

0 0 0 0 0 1 0 1 1 1 1 1 1 1 0 0 0 1 0 0 0 1 1 0 0 ;

0 0 0 0 0 0 0 0 0 1 1 0 1 1 0 0 0 0 0 0 1 1 1 0 0];

Can we only extract existing values of 1 from many rows? For examples the result is:

Result = [

0 0 0 0 0 0 0 0 0 1 1 0 1 1 0 0 0 0 0 0 0 0 1 0 0];

Only one row. Without looping and IF.

*note: The matrix A is only for display. We can copy and paste, but need to adjust the matrix.
