Evaluate the value of an arithmetic expression in Reverse Polish Notation. (Medium)Valid operators is + , - , * , / . Each operand is an integer or another expression.Some Examples: ["2", "1", "+", "3", "*")--((2 + 1) (3)-9 ["4", "", "5", "/", "+"], 4 + (13/5))Analysis:Based on the inverse Polish expression definition, set up the stack-up numberTraversing strings, encountering numbers, entering the stack, encountering operators, removing the top two elements of the stack, and then loading the

The principle is described in Wikipedia as follows: The R tokens are placed in the bucket every second, i.e. a token is placed in the bucket every 1/r seconds. A bucket can hold a maximum of B tokens. When a token is placed in a b
