The hardest part of writing a loop...
is knowing how to write the condition that will keep the loop going.

The way to write a loop to make a Jeroo keep hopping until it finds water in front of it is:

• while there is NOT water ahead
  • hop

So, the condition to keep going is the opposite of the condition to stop!

Fill in the missing conditions to keep each of these loops going. The first example has been filled in for you

while(!isWater(AHEAD)) 

while(               )

while(               )

while(               )
