Basically, we use the idea that we can represent a subset of the array as 0’s and 1’s , there will be total n bits, ‘1’ at the ith bit indicates that the ith element is chosen for the current subset, and 0 indicates that it is …
WebbYou are given two 32-bit numbers N, M and two bit positions i and 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 atleast 5 bits between i and j. Webb5 maj 2024 · Below are simple steps to find the value of k-th bit. 1) Left shift given number 1 by k-1 to create a number that has only set bit as k-th bit. temp = 1 << (k-1) 2) Return bitwise XOR of temp and n. Since temp has only k-th bit set, doing XOR would toggle only …
