The prefix infix suffix expression in computer is an important application of data structure stack, they are the notation of the expression, but the relative position is not the same as the name implies, the prefix expression refers to the symbols are in the operand before the infix expression refers to operators are operands, after the suffix expression is after. Such as: (a+b) *c-d is an infix expression

say a few, it must be split into several three, and the rest is split into two. the requirements for this question cannot be the same, so it must be arranged in the order of 2, 3, and 4. Starting from 2, it will make it smaller, so that the number will be the most, and adding one at a time will make him closer and closer. So with prefix and record, if there is surplus, it must be from the back one by one + 1, and the remaining number can be at most =
