Working Backward with a Max-Heap

  1. Calculate the sum of all elements in the target array.
  2. Create a max-heap and add all elements of the target array to it.
  3. While the maximum element in the heap is greater than 1: a. Extract the maximum element from the heap. b. Calculate the new value for the extracted element using modulo operation with the sum of the remaining elements. c. If the new value is less than 1 and the heap size is greater than 1, return false. d. Update the sum with the new value. e. Insert the new value back into the heap.
  4. If the loop completes, return true as all elements have been reduced to 1.
