My code is failing 1 test case and i am unable to find why so?
Have debugged your code here, have just increased size too 700000
Why have you increased the size of the array ?
It’s cause of the constraints given in the question the desired size would be 700000
But here it is showing 500000
It’s not mentioned in the question but the prime number
will be of order 10^7 but in your code you were only checking prime till 500000
So that’s why one case was failing
