Why is the .bss segment required?
...efore main() is called. It will typically go like this pseudo:
for(i=0; i<all_explicitly_initialized_objects; i++)
{
.data[i] = init_value[i];
}
memset(.bss,
0,
all_implicitly_initialized_objects);
Where .data and .bss are stored in RAM, but init_value is stored in ROM. If i...

What is better, adjacency lists or adjacency matrices for graph problems in C++?
...ind the "breakpoint" where a list takes up more memory than a matrix:
8e > n2/8 when d > 1/64
So with these numbers (still 32-bit specific) the breakpoint lands at 1/64.
If the density (e/n2) is bigger than 1/64, then a matrix is preferable if you want to save memory.

Ukkonen's suffix tree algorithm in plain English
... the text. In this sense, each
edge carries a string label of arbitrary length, but takes only O(1)
space (two pointers).
Basic principle
I would like to first demonstrate how to create the suffix tree of a
particularly simple string, a string with no repeated characters:

The result 1605 is correct
