// Loops Test

// Test 1: Continue in repeat
repeat 5 times with i:
  if i equals 2 then:
    continue
  print "i: " + i
// Output: i: 0, i: 1, i: 3, i: 4

// Test 2: Continue in while
set x to 0
while x < 5:
  change x by 1
  if x equals 3 then:
    continue
  print "x: " + x
// Output: x: 1, x: 2, x: 4, x: 5

// Test 3: Continue in count
count with n from 1 to 5:
  set rem to n mathModulus 2
  if rem equals 0 then:
    continue
  print "odd: " + n
// Output: odd: 1, odd: 3, odd: 5

// Test 4: Nested loops with continue
repeat 3 times with i:
  repeat 3 times with j:
    if j equals 1 then:
      continue
    print i + "," + j
// Output: 0,0  0,2  1,0  1,2  2,0  2,2
