A substring is a group of contiguous characters in a string. For instance, all substrings of abc are [a, b, c, ab, bc, abc]. Given a binary representation of a number, determine the total number of substrings present that match the following conditions: 1. The 0s and 1s are grouped consecutively (e.g., 01, 10, 0011, 1100, 000111, etc.). 2. The number of 0s in the substring is equal to the number of 1s in the substring. Example: s = 001101 The 4 substrings matching the two conditions include [0011, 01, 10, 01]. Note that 01 appears twice, from indices 1-2 and 4-5. There are other substrings, e.g., 001 and 011 that match the first condition but not the second.
