Can you provide a code to remove characters from given string whose frequencies are a Prime Number and the other steps required given the following:
Remove characters from given string whose frequencies are a Prime Number | Function to perform the seive of eratosthenes algorithm.
Initialize all entries in prime [ ] as true.
Initialize 0 and 1 as non prime.
Traversing the prime array.
If i is prime.
All multiples of i must be marked false as they are non prime.
Function to remove characters which have prime frequency in the String.
Length of the String.
Create a bool array prime.
Sieve of Eratosthenes.
Stores the frequency of character.
Storing the frequencies.
New String that will be formed.
Removing the characters which have prime frequencies.
If the character has prime frequency then skip.
Else concatenate the character to the new String.
Print the modified String.
Driver Code.

#Here is code to remove characters from given string whose frequencies are a Prime Number and the other steps required.
 def SieveOfEratosthenes ( prime , n ) :
	for i in range ( n + 1 ) :
		prime [ i ] = True
	prime [ 0 ] = prime [ 1 ] = False
	i = 2
	while i * i <= n :
		if ( prime [ i ] == True ) :
			j = 2
			while i * j <= n :
				prime [ i * j ] = False
				j += 1
		i += 1
def removePrimeFrequencies ( s ) :
	n = len ( s )
	prime = [ False ] * ( n + 1 )
	SieveOfEratosthenes ( prime , n )
	m = { }
	for i in range ( len ( s ) ) :
		if s [ i ] in m :
			m [ s [ i ] ] += 1
		else :
			m [ s [ i ] ] = 1
	new_String = " "
	for i in range ( len ( s ) ) :
		if ( prime [ m [ s [ i ] ] ] ) :
			continue
		new_String += s [ i ]
	print ( new_String , end = " " )
