Description:
2 (Printing four patterns using loops)
Use nested loops that print the following patterns in four separate programs:

Pattern I       Pattern II     Pattern III     Pattern IV
1               1 2 3 4 5 6              1     1 2 3 4 5 6
1 2             1 2 3 4 5              2 1       1 2 3 4 5
1 2 3           1 2 3 4              3 2 1         1 2 3 4
1 2 3 4         1 2 3              4 3 2 1           1 2 3
1 2 3 4 5       1 2              5 4 3 2 1             1 2
1 2 3 4 5 6     1              6 5 4 3 2 1               1
