Hello! Has anyone resolved the exercise on their first try ? I had some basic idea on how to solve but apparently it was at most 10% of the entire exercise solution and the solution that Mosh provided left me starring at the monitor …

Hi.  
It took me 5 minutes. That is my first try. I am not sure if that is correct… However:

sentence = “This is a common interview question”  
winner = " "  
summary = 0  
for item in sentence.replace(" ", “”):  
number = sentence.count(item)  
if number \> summary:  
summary += number  
winner = item, number

print(winner)
