Question 546400
.


In his solution, @mananth used a computer code (which he used practically in all his posts).


One of typical errors this code makes regularly is incorrect reading input data from original posts.


But @mananth never (or very rare) checks what the code produces, 
so this is a source of many his faults.



Solutions of the other person, @lwsshar3, who also systematically uses a computer code,
suffer of the same deficiency.
