C# quickest way to shift array

Question

How can I quickly shift all the items in an array one to the left, padding the end with null?

For example, [0,1,2,3,4,5,6] would become [1,2,3,4,5,6,null]

Answer 1

Can't you

• allocate the array with an extra 1000 elements

• have an integer variable int base = 0

• instead of accessing a[i] access a[base+i]

• to do your shift, just say base++

Then after you've done this 1000 times, copy it down and start over.
That way, you only do the copy once per 1000 shifts.

Q: How many IBM 360s does it take to shift a register by 1 bit?
A: 33. 32 to hold the bits in place, and 1 to move the register. (or some such...)
