C++ - Maximum and Minimum in array.cpp

/*
program to find maximum and minimum in array

STL library of C++ provides builtin method to find maximum and minimum in array,vector,string and many other data structures

#include<algorithm>
int mx=*max_element(ar,ar+n) // n is length of array
int mx=*max_element(vec.begin(),vec.end()) // for vector and string

similarly minimum can be found just replace max with min
