WebNow you have to declare the main () function and inside that main () definition, declare a variable of type integer with name 'n'. Then using cout<<""; prints the string "Enter the Number : ". The cin statement is used to read the value from the keyboard. Then a for loop will be implemented which will count from 2 till n-1. 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
