Given an array of integers, every element appears thrice except for one which occurs once. Find that element which does not appear thrice.

Given an array of integers A, every element appears twice except for one. Find that single one. NOTE: Your algorithm should have a linear

Given an integer array A of size N. You need to find the value obtained by XOR-ing the contiguous subarrays, followed by XOR-ing the values

Given an integer A find the Ath number whose binary representation is a palindrome. NOTE: Consider the 1st number whose binary representat

Given a positive integer A, the task is to count the total number of set bits in the binary representation of all the numbers from 1 to A.

Given an integer array A of N integers, find the pair of integers in the array which have minimum XOR value. Report the minimum XOR value.

We define f(X, Y) as number of different corresponding bits in binary representation of X and Y. For example, f(2, 7) = 2,

Divide two integers without using multiplication, division and mod operator. Return the floor of the result of the division.

Reverse the bits of a 32-bit unsigned integer A. To solve this problem first find the positions of set bits in the original number then

Given a number, count the number of set bits.
