int main()
{
std::vector<int> v = {2, 1, 3, 6, 7, 9, 8};

int min = *min_element(v.begin(), v.end());
std::cout << min << ", " << max << std::endl; // 1, 9

}To be used in DP problems:
vector<vector<int>>dp; //global init
dp = vector<vector<int>>(n,vector<int>(m,0)); // local init for test cases
where,
n, m = dimensions of matrixauto M = 4; // num of rows
auto N = 3; // num of cols in each row
auto default_value = 1; // default value of all int elements
std::vector<std::vector<int>> matrix(M, std::vector<int>(N, default_value));vector<vector<int>> vec( n , vector<int> (m, 0));
where: n is number of ROWS,
m is number of COLUMNS
So result will be ( Let n = 2, m = 3 )
[[ 0, 0, 0],
[ 0, 0, 0]]
( 2 x 3 )vector<vector<int> > vec( n , vector<int> (m, 0));vector<vector<int> > v2(8, vector<int>(5));
