WebFew prime number are − 1, 2, 3, 5 , 7, 11 etc. Algorithm Algorithm of this program is very easy − START Step 1 → Take integer variable A Step 2 → Divide the variable A with (A-1 to 2) Step 3 → If A is divisible by any value (A-1 to 2) it is not prime Step 4 → Else it is prime STOP Pseudocode WebWhat is the time complexity of the algorithm to check if a number is prime? This is the algorithm : bool isPrime (int number) { if (number < 2) return false; if (number == 2) return true; if (number % 2 == 0) return false; for (int i=3; (i*i) <= number; i+=2) { if (number % i == 0 ) return false; } return true; } algorithms complexity numbers
