In MATLAB, primes(N) provides all the prime numbers less than or equal to N. E.g. primes(15) = [2 3 5 7 11 13]. The sum of the first digit of each prime is 19 (i.e. 2+3+5+7+1+1 = 19). What is the sum of the first digit of all primes less than or equal to 33333? You may want to use the num2str() function.
