Shows the graph of locals() and blocks.

Shows the graph of mg.stack() and blocks.

Builds the graph of 'nodes' in 'graphviz_graph' starting at 'root_id' where 'id_to_slices' indicates what is visible in the graph.

Recursively builds the graph starting at 'node_id' and adds it to 'graphviz_graph'.

Adds whitespace to caret line in 's' so it is as long as the previois line.

Sorts `data` to the digit at position `digit` using stable Counting Sort. The sorted data is writen to `data_new`.

Sorts `data` to the digit at position `digit` using stable Counting Sort. The sorted data is writen to `data_new`.

Creates a dictionary that maps each depth to the nodes at that depth.

Creates and returns a memory graph from 'data'.

Copies 'digits' but shares 'letters'.

Copies 'digits' but shares 'letters'.

Returns the Node for 'data' based on it's id or type.

Convert data to string.

'path' is mutable to minimize copying

Embed keys in Node_Key_Value nodes, so that the keys are not shown as separate nodes.

Helper function to convert the traceback of an exception to a string.

Fill the HTML_Table object with each child of the node.

Helper function to fill the html_table with the children of the Node_Base in horizontal orientation.

Helper function to fill the html_table with the children of the Node_Base in horizontal orientation.

Helper function to fill the html_table with the children of the Node_Base in vertical orientation.

Helper function to fill the html_table with the children of the Node_Base in vertical orientation.

Searched and returns the (row, col) of the empty space (EMPTY_TILE).

Helper function to format 'value' to be shown in the graph. We escape html characters and convert newlines to <BR/> tags.

Get the edges that need to be added to connect the table to other tables in the graph.

Return the (row, col) of the empty space (EMPTY_TILE).

Returns a dict value->counts of 'values'.

Return the HTML_Table object that determines how the node is visualized in the graph.

Return a label for the node to be shown in the graph next to the HTML table.

Get the maximum value of the number of columns of rows in the table.

Generates a list of `n` random integers with `bit_blocks` x `NR_BITS` bits.

Generates a list of `n` random integers in range [rand_min,rand_max).

Generates a list of `n` random integers with `nr_digits` digits.

Reconstruct the path from the initial board to the solution.

Helper function to get the source location of the stack with 'stack_index' of the call stack.

Return if the node has references to other nodes.

Return if the node has references to other nodes.

Return if the node is the root node.

Return if the node is vertical or horizontal based on the orientation of the children.

Return if the node is vertical or horizontal based on the orientation of the children.

Build a decision tree from training data. Args: data: List of data points where each point is [class_label, feature1, fea

Limit the length of a string s to the 'max_string_length' in the config.

Returns a dict coin->count to make 'amount'.

Recursively reads through each reference found in 'data', creates a node for it and adds, and adds it to 'nodes'.
