**Arrays Introduction C++**

### Problem Statement :

An array is a series of elements of the same type placed in contiguous memory locations that can be individually referenced by adding an index to a unique identifier. For arrays of a known size, 10 in this case, use the following declaration: int arr[10]; //Declares an array named arr of size 10, i.e, you can store 10 integers. Note Unlike C, C++ allows dynamic allocation of arrays at runtime without special calls like malloc(). If n = 10 , int arr[n] will create an array with space for 10 integers. Accessing elements of an array: Indexing in arrays starts from 0.So the first element is stored at arr[0],the second element at arr[1] and so on through arr[9]. You will be given an array of N integers and you have to print the integers in the reverse order. Input Format The first line of the input contains N , where N is the number of integers.The next line contains N space-separated integers. Constraints 1 <= N <= 1000 1 <= A[i] <=1000 Output Format Print the N integers of the array in the reverse order, space-separated on a single line.

### Solution :

` ````
Solution in C :
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
int main() {
int n;
cin >> n;
int arr[n];
for (int i = 0; i < n; i++)
cin >> arr[i];
for (int i = n - 1; i >= 0; i--)
cout << arr[i] << ' ';
return 0;
}

## Truck Tour

Suppose there is a circle. There are N petrol pumps on that circle. Petrol pumps are numbered 0 to (N-1) (both inclusive). You have two pieces of information corresponding to each of the petrol pump: (1) the amount of petrol that particular petrol pump will give, and (2) the distance from that petrol pump to the next petrol pump. Initially, you have a tank of infinite capacity carrying no petr

The median of a set of integers is the midpoint value of the data set for which an equal number of integers are less than and greater than the value. To find the median, you must first sort your set of integers in non-decreasing order, then: If your set contains an odd number of elements, the median is the middle element of the sorted sample. In the sorted set { 1, 2, 3 } , 2 is the median.

Tieu owns a pizza restaurant and he manages it in his own way. While in a normal restaurant, a customer is served by following the first-come, first-served rule, Tieu simply minimizes the average waiting time of his customers. So he gets to decide who is served first, regardless of how sooner or later a person comes. Different kinds of pizzas take different amounts of time to cook. Also, once h
