how to use modulo operator code example

Example: modulo operator

Example: 5 % 2 = 1
Think about it like this:

  Of 5 items, remove as many sets of 2 as you can. Whatever item(s) remains
  is the answer, aka the remainder.

Visual example of 5 % 2:

  Start with 5 items:

    item1, item2, item3, item4, item5
   
  Remove 2:
  
  	item3, item4, item5
  
  Remove another 2:
  
	item5
    
  No more sets of 2 can be removed and there is 1 item remaining. So the answer
  would be 1
  
More general:
n % m
	
  Of n items, choose as many sets of m as you can. Whatever item(s) remains
  is the answer, aka the remainder.
