Recently I was trying to count the number of n-bit numbers that have an equal number of 1′s and 0′s. For example, there are 6 such numbers for 4-bit long numbers (0011, 0101, 0110, 1001, 1010, 1100). I wrote a simple program to count such numbers for arbitrarily long numbers. However, the program was computationally [...]
