Two brackets are considered to be a matched pair if the an opening
bracket (i.e., (, [, or { ) occurs to the left of a closing bracket (i.e., ),
], or }) of the exact same type. There are three types of matched
pairs of brackets: [], {}, and (). A matching pair of brackets is not
balanced if the set of brackets it encloses are not matched. WAP to
determine whether the input sequence of brackets is balanced or not.
If a string is balanced, it print YES on a new line; otherwise, print
NO on a new line.
Example: Input: {[()]} and Output: YES
Input: {[(])} and Output: NO

i. Write statements in C++ that would execute Function 1 and Function 3 of class Seminar.
ii. In Object Oriented Programming, what is Function 4 referred as and when does it get invoked/called?
iii. In Object Oriented Programming, which concept is illustrated by Function 1 and Function 3 together?
2. The sequence of natural numbers a1, a2, ..., an is given. Replace the terms greater than the given number Z. with this number. Calculate the number of substitutions.
3. The sequence of natural numbers a1, a2, ..., an is given. There are positive and negative elements in the chain. Calculate the product of negative elements P1 and the product of positive numbers P2. Compare the modules P2 and P1, indicate which of the modulus is greater.
Your task is to then create a java program that when given an acronym with its meaning plus some sentence, the program replaces the first occurrence of the acronym in the sentence with its meaning.
Sample run 1:
Enter an acronym and its meaning (separated by spaces): NUST Namibia University of Science and Technology
Enter a sentence: Welcome to my NUST. Output: Welcome to my Namibia University of Science and Technology.
