this one is just awesome!

Normally 'int sum' would store garbage value and should be done like this 'int sum = 0'

Don't think var name matters in such simple solutions. 'tot'|'sum' definetely better here but...

for C the task isn't very descriptive. Does not say you have to copy number to the given count array. what for? task says populate.

yep, this one is incorrect

neat one

comparing first and last char also lets one pass the test. thou that's not what it is about.

I tried to find out if it is and just decided to leave it there. Is it because function exits after return? Does allocated men get free after that?

What "break" is not used here? What am i missing?

elegant one!

that's obviously a joke %) no hard feelings
