dimention vector python code example

Example 1: c++ vector pop_back

#include <bits/stdc++.h> 
using namespace std;
int main(){
    vector<int> v1{10, 20, 30, 40, 50};
    
    //removing elemenets
    v1.pop_back();  //removes 50
    v1.pop_back();  //removes 40

}

Example 2: java vector push_back

// push_back equivalent
ArrayList<int> a = new ArrayList<int>();
a.add(2);             // Add element to the ArrayList.
a.add(4);

// pop_back equivalent.
a.remove(a.size()-1); // Remove the last element from the ArrayList.
