Mystery Sandwich Sudoku

This is a variant of Sandwich Sudoku. Three variants of sandwich rules appear and require the puzzle solver to judge for themselves: Standard Sandwich Sudoku, Sandwich "肉夹馍（RouJiaMo）", Sandwich "春卷（ChunJuan）".

The usual sudoku rules apply.

The external prompt clue is the largest prompt number that meets the three rules.

1、Standard Sandwich Rules: A number clue outside a row or column is the sum of the digits between the 1 and the 9 in that row or column.

2、Sandwich Sudoku--肉夹馍（RouJiaMo）Rules:The number indicated outside the box represents the sum of other numbers between the first number in the row and the number one greater than it.

3、Sandwich Sudoku--春卷（ChunJuan）Rules:The number outside the box represents the sum of the numbers between the largest number and the smallest number in the first 6 cells of the row and column from that position.

This is the main dish, welcome to enjoy！
