Can you provide a code to minimum number of single digit primes required whose sum is equal to N and the other steps required given the following:
Minimum number of single digit primes required whose sum is equal to N | function to check if i - th index is valid or not.
function to find the minimum number of single digit prime numbers required which when summed up equals to a given number N ..
Not possible.
Driver Code"
How can the above be solved in Python?
