title: Java Questions
body: <p>I'm TAing for an introductory course in Java for freshmen. So, far we've learnt most of Java except the OOPS part. Like we can do methods, loops, control stuctures, arrays, strings, recursion etc..
  Since this is their first programming course, they are not aware of fancy datastructures yet. </p>
  
  <p>I have dont most of the regular programs like factorial, fibonacci, primes etc..</p>
  
  <p>I'm looking for some interesting problems in the space without using complex datastructures. Any ideas would be super helpful.</p>
  
  <p>thanks, Vinbot</p>
