I need it now!!!

Question

length = strlen(str)

for(i = 0; i < length; i++)

{

symb = paranthesis[i];

if(symb == '_____' && stack_size == ____ )

top = push(top,symb);

else if(symb == '____' && stack_size == _____)

break;

else if(symb == '____')

top = push(top,symb);

else if(symb == '_____ ' && top->ps == " ______")

top = ______(_____)

}

if(i == length && stack_size == _____)

printf("The String is valid");

}

Answer 1

Not a fan of fill in the blank programming....

what is this block supposed to do?

looks like it validating an arithmetic expression, and

your checking if the parenthesis are balanced....

no need for the stack, just count the parenthesis of any type,

both ) and (. There must be an EVEN # of them
