Solution

One of the skills for this question is being able to quickly read between the lines to know what the problem is; since only the first character in the strings can be converted, check every second-and-onward character in all the T strings for a given problem, and if any are uppercase, this problem can't be solved, otherwise increment a running total somewhere.
