Description : The C++ function std::is_sorted checks if the elements in range [first, last] are sorted in ascending order. If the elements are sorted in ascending order, the function returns true, else returns false.
Example :
int main(){
std::vector<int> v = {1, 5, 12, 17, 21, 35};
if(is_sorted(v.begin(), v.end())){
std::cout << "Vector is sorted\n";
}
else{
std::cout << "Vector is not sorted\n";
}
return 0;
}
