Given a n x n matrix where each of the rows and columns are sorted in ascending order, find the kth smallest element in the matrix. Note that it is the kth smallest element in the sorted order, not the kth distinct element. Example: matrix = [ [ 1, 5
把Go程序变小的办法是: go build -ldflags “-s -w” (go install类似) -s去掉符号表(然后panic时候的stack trace就没有任何文件名/行号信息了, 这个等价于普通C/C++程序被strip的效果), -w去掉DWARF调试信息,得到的程序就不能用gdb调试了. 比如,server.go是一个简单的http server,用了net/http包. $ go build server.go $ ls -l server -rwxr-xr-x 1 mi
