title: "CS174: OOP - Drills - Array Min Index"


info:
  prev: "./Array3Sort"
  instructions: "Create a static method <code>getMinIndex</code> takes in an array of doubles and returns the index of the minimum element in the array.  You must handle the following two special cases: <ol><li>If there are ties, it should return the lowest index among the ties</li><li>If the array is empty, your program should return 0 without crashing</li></ul>"
  goals:
    - To do proper array indexing
    - To use loops in concert with arrays
    - To keep track of multiple auxiliary variables in a loop
    - To properly define methods
