Answer 1

Anuj Khare ,

Try to read your warning you got from the SoloLearn compiler.
Here's what it told me:
```
./Playground/file0.cpp:

5:15: warning: comparison of integer expressions of different signedness: 'int' and

'std::vector<int>::size_type' {aka 'long unsigned int'}

[-Wsign-compare]

5 | for(int i=0;i<v.size();i++)
```
try adding long unsigned to `int i`, at line 5.

Plus, showing us what error you get from the VSCode compiler may help us a lot from answering your questions, since I don't use it.
