Code : Max Priority Queue

 

Implement the class for Max Priority Queue which includes following functions -

1. getSize -

Return the size of priority queue i.e. number of elements present in the priority queue.

2. isEmpty -

Check if priority queue is empty or not. Return true or false accordingly.

3. insert -

Given an element, insert that element in the priority queue at the correct position.

4. getMax -

Return the maximum element present in the priority queue without deleting. Return -Infinity if priority queue is empty.

5. removeMax -

Delete and return the maximum element present in the priority queue. Return -Infinity if priority queue is empty.

Note : main function is given for your reference which we are using internally to test the class.









class PriorityQueue {
// Declare the data members here

public:
PriorityQueue() {
// Implement the constructor here
}

/**************** Implement all the public functions here ***************/

void insert(int element) {
// Implement the insert() function here
}

int getMax() {
// Implement the getMax() function here
}

int removeMax() {
// Implement the removeMax() function here
return pq.
}

int getSize() {
return pq.size();
// Implement the getSize() function here
}

bool isEmpty() {
if(pq.size()==0) return 0;
else return true;
// Implement the isEmpty() function here
}
};

Code : All connected components

  Given an undirected graph G(V,E), find and print all the connected components of the given graph G. Note: 1. V is the number of vertices present in graph G and vertices are numbered from 0 to V-1. 2. E is the number of edges present in graph G. 3. You need to take input in main and create a function which should return all the connected components. And then print them in the main, not inside function. Print different components in new line. And each component should be printed in increasing order (separated by space). Order of different components doesn't matter. Input Format : The first line of input contains two integers, that denote the value of V and E. Each of the following E lines contains two space separated integers, that denote that there exists an edge between vertex a and b. Output Format : Print different components in new line. And each component should be printed in increasing order of vertices (separated by space). Order of different components doesn't matter....

Coding Ninjas

  Given a NxM matrix containing Uppercase English Alphabets only. Your task is to tell if there is a path in the given matrix which makes the sentence “CODINGNINJA” . There is a path from any cell to all its neighbouring cells. For a particular cell, neighbouring cells are those cells that share an edge or a corner with the cell. Input Format : The first line of input contains two space separated integers N and M, where N is number of rows and M is the number of columns in the matrix. Each of the following N lines contain M characters. Please note that characters are not space separated. Output Format : Print 1 if there is a path which makes the sentence “CODINGNINJA” else print 0. Constraints : 1 <= N <= 1000 1 <= M <= 1000 Time Limit: 1 second Sample Input 1: 2 11 CXDXNXNXNXA XOXIXGXIXJX Sample Output 1: 1 bool hasPath ( vector < vector < char >> & board , int n , int m ) { // Write your code here. } #include < iostream > #include ...
