i starts at 0 and ends at 2 (because at 3 the condition i <3 is already violated). Those. total i takes 3 values.

Similarly for j. 3x3 = 9.

    • i = 0:
      1. j = 0
      2. j = 1
      3. j = 2
    • i = 1:
      1. j = 0
      2. j = 1
      3. j = 2
    • i = 2:
      1. j = 0
      2. j = 1
      3. j = 2

    TOTAL: 9 times
