Having a hard time with the test suite regarding the number of hours in one year. I think it should be 8 765.81277h/y

It's a fun problem

the test suits are all passed , but the mathworks net tells its wrong.
and the size is '-1'.
i use the datenum function.

Sanzhar Askaruly on 6 Jul 2019

using existing functions makes this trick easy

Laza Álmos on 27 Mar 2020

with an existing funcion it is solveable

Bugrahan Atar on 9 Feb 2021

function elapsed= elapsed_time(d1,d2)
d1='2010/12/14 12:00:00'
d2='2010/12/15 13:06:36'
a=(str2num(d2(1:4))-str2num(d1(1:4)))*8760;
b=(str2num(d2(6:7))-str2num(d1(6:7)))*720;
c=(str2num(d2(9:10))-str2num(d1(9:10)))*24;
e=str2num(d2(12:13))-str2num(d1(12:13));
f=(str2num(d2(15:16))-str2num(d1(15:16)))/60;
g=(str2num(d2(18:19))-str2num(d1(18:19)))/3600;
elapsed=a+b+c+e+f+g
end

it told me that solution is wrong?

This test program is wrong.To judge a leap year, you need to calculate if the following condition is satisfied mod(year,4)==0 & mod(year,100)~=0 & mod(year,400)==0. However, this team only count those years that mod(year,4)==0
