Design an arithmetic expression tree for the given expression: $(y**(a+b)**(c-d))$

What is the number of nodes in a perfect full binary tree of height $4?$

Evaluate the given postfix expression using stack.

$6523+8**+3+**$

There are $8$ elements Hash Table that result from using the hash function,

$h(k)=k^{**}2$mod$7$
