  3. for every row count the same consecutive number and print the count first and then the number

    line 1 : 1 1
    line 2(2 times 1) : 2 1
    line 3(1 time 2 and 1 times 1) : 1 2 1 1
    line 4(1 times 1, 1 times 2 and 2 times 1) : 1 1 1 2 2 1
    line 5(3 times 1 2 times 2 and 1 times 1): 3 1 2 2 1 1
    Similarly:
    line 5 : 1 3 1 1 2 2 2 1

  5. 5th row is :2 2 1 1 1 1 1 2 1 1
    6th row is : 1 1 2 1 1 2 2 1 1 1 1 1 1 2 2 1

    1. Start off with 2 rows first

    1 1
    2 1

    2. To get the 3rd row:
    - Divide previous row(2nd row) into 2 equal parts and then switch places
    1 2
    - Add the the previous to previous row(1st row) to the end of it.
    1 2 1 1
    3. To get the 4th row:
    - Divide the 3rd row into 2 equal parts and switch places
    1112
    - Add the 2nd row to the end
    1 1 1 2 2 1
    4. To get the fifth row:
    - Divide the 4th row into 2 equal parts and switch places
    221111
    - Add the 3rd row to the end
    2 2 1 1 1 1 1 2 1 1

    5. To get the 6th row..... do the same thing
    1 1 2 1 1 2 2 1 1 1 1 1 1 2 2 1
