Problem Statement

Show a nested loop which searches a two-dimensional array filled with random numbers uniformly distributed over

[ 1 , … , 20 ]

{\displaystyle [1,\ldots ,20]}

. The loops iterate rows and columns of the array printing the elements until the value

20

{\displaystyle 20}

is met. Specifically, this task also shows how to break out of nested loops.

Let's start with the solution:

Loop, 10
{
  i := A_Index
  Loop, 10
  {
    j := A_Index
    Random, a%i%%j%, 1, 20
  }
}

Loop, 10
{
  i := A_Index
  Loop, 10
  {
    j := A_Index
    If (a%i%%j% == 20)
      Goto finish
  }
}

finish:
  MsgBox % "a[" . i . "][" . j . "]" is 20
Return
