EMIRP

Emirp Number – Explanation What is an Emirp Number? An Emirp number is a special type of prime number. Conditions: The number itself must be prime Its reverse must also be prime The reversed number should be different from the original Example: 17 → Prime Reverse (71) → Prime 17 ≠ 71 → Valid Emirp So, 17 is an Emirp number PYTHON : def prime(no): div=2 while div < no/2: if no % div == 0: return False div += 1 return True def reverse(no): rev = 0 while no > 0: rev = rev * 10 + no % 10 no = no // 10 return rev num = 17 if prime(num) and prime(reverse(num)): print(num, "is emirp") else: print(num, "is not emirp") Start ↓ Take number (17) ↓ Check if prime → YES ↓ Reverse number → 71 ↓ Check reverse is prime → YES ↓ Both true → Emirp number ↓ End JAVA SCRIPT CODE : function prime(no) { let div = 2; while (div < no / 2) { if (no % div === 0) { return false; } div++; } return true; } function reverse(no) { let rev = 0; while (no > 0) { rev = rev * 10 + (no % 10); no = Math.floor(n
