The value of the given prefix expression *2 / 8 4 3 is calculated to be; 1
<h3>How to work with preorder transversals?</h3>
We are given the expression; *2 / 8 4 3
We will start from the rightmost operation symbol.
For every operation symbol, the two integers following the operation symbol are the symbols on which the operation needs to be performed. Then we replace the operation symbol with the two following integers by the result of the operation.
Then we repeat for the rightmost operation symbol in the remaining string.
*2 / 8 4 3
8 / 4 = 2
⇒ *2 2 3
2 * 2 = 4
4 - 3 = 1
Thus the value of the prefix expression is then 1.
