Replace binary values with varying binary values

Hello,

I have an array of 32 bit binary numbers and I want to replace the last bits with varying lengths of binary numbers.

10111 10110 In this I only change the last bit

10011 10000 In this one I only change the last 2 bits

and so on

What is the question exactly?

[lavanya vs]

'11100001000' Now I want to change the last 4 bits for the first value

3 bits for the second value

1 bit for the third value depending on the count of the bits I need

'11100001001' to replace.

'11100001010'

'11100001011'

'11100001100'

'11100001101'

'11100001110'

'11100001111'

I still don't understand the question. The example looks like a simple count from 1800, 1801, ..., 1807 in binary.

I want to encode the last few bits based on a mapping ( using LSB)
