Show me the steps to solve Chained allocation is a simple file allocation method, which is part of file management.

Illustrate by sketching a diagram $($which includes File Allocation Table$)$ on the following

scenario using chained allocation method:

$$ FileA is having a start block of $0$ and a length of $3$

$$ FileB is having a start block of $8$ and a length of $5$

$$ FileC is having a start block of $9$ and a length of $2$

$$ Block $2$ to block $6$ is currently used by other files
