Write a program to find maximum and minimum in array.

Given an array we have to find the maximum and minimum of array and print the result.

Example:

input:arr[]={67,34,23,56,8}

output:8

Logic:

step 1- declare the max and min variable.
step 2-compare the max and min value with the array value 
step 3- update max and min value 
#include<bits/stdc++.h>
using namespace std;
int main()
{
    int arr[]={67,2,3,5,9};
    int n= sizeof(arr)/sizeof(arr[0]);
    int max=INT_MIN;
    int min=INT_MAX;
    for(int i=0;i<n;i++)
    {
        if(arr[i]<min)
        {
            min=arr[i];
        }
        if(arr[i]>max)
        {
            max=arr[i];
        }
    }
    cout<<"max "<<" "<<max<<endl;
    cout<<"min "<<" "<<min<<endl;
}

Output:

max  67
min  2

Time Complexity-O(N)

space complexity-O(1)
