At first it looked like there were several lines of data (ignoring the first two lines), but there is only one, and the pieces of sequence are actually on the same line, separated by spaces. So if what you call "missing characters" are actually spaces in the output that's because they are already there in the input.

If that's not the issue, you'll have to show the expected output and the one you actually get.
