About
leetcode_solutions_go
is a set of my solutions to the programming challenges at LeetCode, implemented in Go. Originally, I implemented solutions in C++/C, and then re-wrote them with Go. Please go to solutions in C++/C for the description of each problem.
Run
go test
Debug
We can use gcc
to debug Go programs. However, go test -c
generated test executable always has optimization. We can't debug the test executable directly. We have to copy code to main.go and compile code without optimization by go build -gcflags "-N -l"
. Then run gcc leetcode_solutions_go
. I found gcc -tui leetcode_solutions_go
is better.
Performance (Go vs C++/C)
I compaired the performance after I converted 50 questions from C++/C to Go. time ./main
for C++/C version shows real 0m0.010s
, and go test
for Go version shows ok github.com/vinceyuan/leetcode_solutions_go 0.049s
on my MacBook Pro 13-inch 2012. I think one of the reasons the Go version is much slower, is I use slices to replace vector/stack/queue of C++.
