the write function can only write, positive numbers and not negative :-(
Other wise the template is pretty good.
I am getting this error. Can any1 help?
I am using VS Code.
error: 'vector' does not name a type; did you mean 'wctob'?
typedef vector VI;
^~~~~~
wctob
Also ,Let me explain a bit more, I am using these typedefs:
typedef long long ll;
typedef long double ld;
typedef pair<int, int> PII;
typedef vector VI;
typedef vector VS;
typedef vector VII;
typedef vector VVI;
it's throwing above type of error for every other typedef except the first two ones i.e typedef long long ll;, typedef long double ld;
it's throwing above type of error for every other typedef except the first two ones i.e typedef long long ll;, typedef long double ld;
You need to define contents of vector like vector<int>
, vector<string>
, etc as compiler doesn't know what type of vector you are talking about.
You can use header #include <bits/stdc++.h>
it contains all the standard libraries of C++.

How to load the template each time you run or create any new file in vscode ?
You can write a code snippet and use it every time you create a file for CP
/******* Debugging Class Template *******/
#define DEBUG
#ifdef DEBUG
#else
#define debug(args...) // Just strip off all debug tokens
#endif
i really didn't understand this part!
