Sum and Product of Prime Frequencies of Characters in a String | Function to create Sieve to check primes.
false here indicates that it is not prime.
If prime [ p ] is not changed , then it is a prime.
Update all multiples of p , set them to non - prime.
Function to find the sum of prime frequencies of the characters of the given string.
map is used to store character frequencies.
Traverse the map.
If the frequency is prime.
Driver code"
How can the above be solved in Python?
 ... Write me a code to sum and Product of Prime Frequencies of Characters in a String and the other steps required?
