title: A good hash function to use in interviews for integer numbers, strings?
body: <p><br>
  I have come across situations in an interview where I needed to use a hash function for integer numbers or for strings. In such situations which ones should we choose ? I've been wrong in these situations because I end up choosing the ones which have generate lot of collisions but then hash functions tend to be mathematical that you cannot recollect them in an interview. Are there any general recommendations so atleast the interviewer is satisfied with your approach for integer numbers or string inputs? Which functions would be adequate for both inputs in an "interview situation"</p>
