Write an algorithm to calculate a postfix expression. Execute your algorithm using the given postfix expression as your input : a b + c d +*f ↑ .
To evaluate a postfix expression by using the given values:
clear the stack
symb = next input character while(not end of input)
{
if (symb is an operand)
push onto the stack;
else
pop two operands from the stack;
result=op1 symb op2;
push result onto the stack;
}
symb = next input character;
return (pop (stack));
The input postfix expression is given as:- ab+cd+*f^
Symb Stack Evaluation a a
b a b
+ pop a and b (a + b) Push (a + b)
c (a + b) c
d (a + b) c d
+ pop c and d (c + d) Push (c + d)
* pop (a + b) and (c + d) (a + b) * (c + d)
f (a + b) * (c + d) f
^ pop (a + b) * (c + d) and f (a + b) * (c + d) ^ f
The result of evaluation is ((a + b) * (c + d)) ^ f
Each data record contains a fixed place in a relative file. Each record ought to have associated with it in integer key value which will help identify this slot. Therefore, this ke
Explain an efficient way of storing two symmetric matrices of the same order in memory. A n-square matrix array is said to be symmetric if a[j][k]=a[k][j] for all j and k. For
Any Binary search tree has to contain following properties to be called as a red- black tree. 1. Each node of a tree must be either red or black. 2. The root node is always b
By changing the NULL lines in a binary tree to the special links called threads, it is possible to execute traversal, insertion and deletion without using either a stack or recursi
Comparison Techniques There are several techniques for determining the relevancy and relative position of two polygons. Not all tests may be used with all hidden-surface algori
Ask consider the file name cars.text each line in the file contains information about a car ( year,company,manufacture,model name,type) 1-read the file 2-add each car which is repr
null(nil) = true // nil refer for empty tree null(fork(e, T, T'))= false // e : element , T and T are two sub tree leaf(fork(e, nil, nil)) = true leaf(
This is the most extensively used internal sorting algorithm. In its fundamental form, it was invented by C.A.R. Hoare in the year of 1960. Its popularity lies in the easiness of i
Which data structure is used for implementing recursion Stack.
Write down the algorithm of quick sort. An algorithm for quick sort: void quicksort ( int a[ ], int lower, int upper ) { int i ; if ( upper > lower ) { i = split ( a,
