I stuck on the exercise at the page of 18 at unit "Arrays and Loops".

I feel the exercise directs me to use while loop but I did not find a way to do that.

Thanks for the help by now.

Show the book and tell exactly what you don't understand.

While loop have 2 patterns:

while someCondition {
  // Do something
}

or

repeat {
  // do something
} while otherCondition

With the first one, someCondition is tested before executing ; so there may be no iteration at all

With the second otherCondition is tested after an iteration is executed: it is thus executed at least once.
