Tamir Suliman submitted a Comment to Solution 1065790 my solution was right and i tested it i m not sure what is going on
function [tf] = is_it_odd(n)
if rem(n,2)>0
tf='true';
else
tf='false';
end
end

Peng Liu submitted a Comment to Problem 43667. Use a timetable to analyze a train timetable (Part 4) Could you be more specific on the underlying relationship between the input (timetable) and output (mean duration)? That is, among which group are you calculating the mean duration? From your example, there are only 2 groups of destinations, i.e., BOS and NYC, but why there are 3 values in the output? What's the mapping behind? Also, your problems including Part 1, 4, 5 are all based on single test, which allows hardcoded solution to lead.
