Attention: Before start debugging, you must to check availability of your C++ debugger tools. Get more information from VSCode documents.
Features
Start Debugging
Generate debugging codes and start a debug session for your solution.
You can run the LeetCode Debugger: Start Debugging command from the command palette (Ctrl/Cmd + Shift + P).
Online/Offline Code Template
Code template is used to generate the debugging code.
Online: Fetching problem from LeetCode. Requires your solution file to start with problem ID, for example, 1.two-sum.cpp (Or you can modify the regular expression for capturing problem ID in extension settings).
Offline: Using your solution code as code template.
Input/Output
You could use the code below to change the input/output:
For INPUT, both std::istream and std::string (input from file) are acceptable, but you can only have ONE input.
For OUTPUT, both std::ostream and std::string (output to file) are acceptable, you can have multiple outputs.
Interactive Problem
Interactive problem is NOT supported yet.
But you can realize the interactive function by yourself! Know more from API and examples. Here is an example for problem 278.
#ifdef LEETCODE_DEFINITION // protection
int firstVersion; // the first bad version
bool isBadVersion(int version) { // realization
return version >= firstVersion;
}
#define LAZY_INTERACTION firstVersion // input firstVersion
#endif
LAZY_INTERACTION means interactive inputs after function's arguments, INTERACTION means interactive inputs before function's arguments, in addition, function with type void () is also acceptable. The example below will help you to understand these stuff.
#ifdef LEETCODE_DEFINITION // protection
int value1, value2; // interactive values
void before() {
value1 *= 2;
}
void after() {
value2 *= value1;
}
#define INTERACTION value1, before // input value1, then call the function 'before()'
#define LAZY_INTERACTION value2, after // input value2, then call the function 'after()'
#endif
class Solution {
public:
int exampleFunction(int v) {
return v * value1 * value2;
}
};
/*
* input:
* 1 // -> value1 -> value1*=2 -> 2
* 2 // -> v
* 3 // -> value2 -> value2*=value1 -> 6
* output:
* 24 // -> v*value1*value2 -> 2*2*6=24
