5.1 You are given two 32-bit numbers, N and M, and two bit positions, land j. Write a method to insert M into N such that M starts at bit j and ends at bit i. You can assume that the bits j through i have enough space to fit all of M. That is, if M = 10011, you can assume that there are at least 5 bits between j and i. You would not, for example, have j = 3 and i = 2, because M could not fully fit between bit 3 and bit 2.
EXAMPLE
Input: N = 10000000000, M = 10011, i = 2, j = 6
Output: N = 10001001100
