What is a code to subarray of size K with prime sum and the other steps required given the following:
Subarray of size K with prime sum | Generate all prime numbers in the range [ 1 , 1000000 ].
Set all numbers as prime initially.
Mark 0 and 1 as non - prime.
If current element is prime.
Mark all its multiples as non - prime.
Function to prthe subarray whose sum of elements is prime.
Store the current subarray of size K.
Calculate the sum of first K elements.
Check if currSum is prime.
Store the start and last index of subarray of size K.
Iterate over remaining array.
Check if currSum.
Driver Code"
How can the above be solved in Python?
