Need Python Code for the following task: Assume the prefix expression is a string of tokens delimited by spaces. The operators are *,/, +, and -, and the operands are assumed to be single-digit integer values. The output will be an integer result. 1. Create an empty stack called group. 2. Convert the string to a list by using the string method split. 3. Reverse the prefix expression. 4. Scan the token list from left to right: (a) If the token is an operand, convert it from a string to an integer and push the value onto the Group. (b) If the token is an operator, *, /, +, or -, it will need two operands. Pop the Group twice. The first pop is the first operand and the second pop is the second operand. Perform the arithmetic operation. Push the result back on the Group. 5. When the input expression has been completely processed, the result is on the stack. Pop the Group and return the value. Write a function EvalutePrefix that takes input, an expression in prefix notation, and return, as output, the computed value of the given expression.
