pushing value to the front of a vector code example

Example: inserting at start in vector c++

// Inserting at start
vector_name.insert(vector_name.begin(), element_to_be_inserted);

// Inserting after xth element
vector_name.insert(vector_name.begin()+(x-1), element_to_be_inserted);

// Inserting at last
vector_name.push_back(element_to_be_inserted);
