Write a program that accepts an arithmetic expression that does not contain parentheses and verifies that is correctly written. It is correctly written if each of the operators in the expression is between two operands preceded and followed by a space: for example 2 * 3 + 5. Output a correct expression to the system console. Otherwise, output the expression up to the point were the first error was detected, then a caret (Shift 6 key stroke), and then the remainder of the math expression. The second line of output, in both cases, should be the number of tokens (operators and operands) that were in the original expression. (Use the split method in the String class.)
