Consider the algorithm for determining whether a sequence of parentheses is balanced (has correct nesting). The pseudo code for this algorithm appears below.
Initialize a boolean variable validExpression to true.
while (there are more symbols in the expression){
look at the next symbol
if symbol is a {, [, or (
push it on the stack
if it is a }, ], or ){ if the stack is empty then return false
else pop the stack
}
if the element popped is not the match for symbol then return false
}
if the stack is not empty then return false, else return true.
Required:
What is the maximum number of symbols that will appear on the stack at any time for the sequence { [ ( ) ] [ ( ) ] [ ( ) ] }? why?
