1. Run Length Decoding for
A4B9C1A1D4E2F1
Format = Character then Count (A4)

Solution:
Run Length Decoding for A4B9C1A1D4E2F1

A4 : A is repeated 4 times = AAAA

B9 : B is repeated 9 times = BBBBBBBBB

C1 : C is repeated 1 times = C

A1 : A is repeated 1 times = A

D4 : D is repeated 4 times = DDDD

E2 : E is repeated 2 times = EE

F1 : F is repeated 1 times = F

So, A4B9C1A1D4E2F1 = AAAABBBBBBBBBCADDDDEEF

2. Run Length Decoding for
4A9B1C1A4D2E7F
Format = Count then Character (4A)

Solution:
Run Length Decoding for 4A9B1C1A4D2E7F

4A : A is repeated 4 times = AAAA

9B : B is repeated 9 times = BBBBBBBBB

1C : C is repeated 1 times = C

1A : A is repeated 1 times = A

4D : D is repeated 4 times = DDDD

2E : E is repeated 2 times = EE

7F : F is repeated 7 times = FFFFFFF

So, 4A9B1C1A4D2E7F = AAAABBBBBBBBBCADDDDEEFFFFFFF
