Let's play with numbers again! An "odven" number is a number that starts with an odd digit and alternating between even and odd digits subsequently. (e.g 123)

💼 TASK
Write a program to accept an integer determine whether it's an odven number. If it's not, display the next odven number.

🔧 TEST CASE
✅ 123
✅ 1234
✅ 1496
✅ 3030
✅ 5298
✅ 72727
❎ 234 ▶ 301
❎ 2345 ▶ 3010
❎ 3239 ▶ 3250
❎ 5005 ▶ 5010

❤ BONUS
Creative and clear-cut approach is encouraged.

Happy Coding!!! 😁💻
