• Strengths:
  • The binary search implementation is correct and efficient.
  • The edge cases are handled well with checks at the beginning and end of the array.
  • The code is clean, readable, and well-commented.
• Areas for Improvement:
  • The return statement return arr[low] - 1; might not work correctly if the missing number is at the end of the array. For example, if the array is {1, 2, 3, 4, 5, 6, 7}, the missing number is 8, but the code will not return the correct result. The reference solution handles this by returning ar[a] + 1, which is more reliable.
  • Consider adding a check to ensure the array is not empty or null, although the problem likely assumes valid input.
