Leetcode Solutions

Two Pointers Approach

  1. Initialize concatenation value to 0.
  2. Set left pointer to the start of the array and right pointer to the end of the array.
  3. While left is less than right: a. Calculate the number of digits in the number at right pointer. b. Calculate the concatenation of the numbers at left and right pointers. c. Add the concatenation to the concatenation value. d. Increment left and decrement right.
