mixStart

Problem:

Return true if the given string begins with "mix", except the 'm' can be anything, so "pix", "9ix" .. all count.

Test Cases:
mixStart("mix snacks") → true
mixStart("pix snacks") → true
mixStart("piz snacks") → false

Solution:

public boolean mixStart(String str) {
  if(str.length()<3)
  {
 
      return false;
 
   
  }
  if(str.length()>=3)
  {
    if(str.substring(1,3).equals("ix"))
    {
      return true;
    }
  }
  return false;
}
