Modify the code of Figure $4\mathrm{.}4($in eBook$)$ to support storing variable$-$length strings

of at most $255$ characters. The stack array should have type char. A string is

represented by a series of characters $($one character per stack element$),$ with the

length of the string stored in the stack element immediately above the string itself,

as illustrated by the figure below. The code should accept an input string from,

$"\{,"\},","(",",",",","]"$ and whether the pairs and the orders of

$"\{,"\},","(,"),","[,"]"$ are correct in exp.

For example, the program should print true for $"$ and false

for exp$=[(])$
