python 3.x – Evaluation of a phrase BST – Daily Coding Challenge

Here is my solution for the Daily Coding Challenge 50

Write a function to evaluate an arithmetic expression in the form of a binary search tree

example

                *
/ 
+ +
/  / 
3 2 4 5

Back >> 45

Is this the most efficient way to do this?

"" Create an operation tree and calculate the result.


Class Tree:
def __init __ (self, value, left = None, right = None):
Initialize values
self.value = value
self.left = left
self.right = correct

def detect_sum (self, total):
if self.left == None and self.right == None:
return int (self.value)
if self.value == "*":
total + = self.left.determine_sum (total) * self.right.determine_sum (total)
if self.value == "+":
total + = self.left.determine_sum (total) + self.right.determine_sum (total)
if self.value == "-":
total + = self.left.determine_sum (total) - self.right.determine_sum (total)
if self.value == "/":
total + = self.left.determine_sum (total) / self.right.determine_sum (total)
total return


if __name__ == "__main__": #
n = tree ("*")
n.left = tree ("+")
n.right = tree ("+")
n.left.right = tree ("+")
n.right.right = tree ("+")

n.left.left = tree ("3")
n.left.right.left = tree ("4")
n.left.right.right = tree ("5")

n.right.left = tree ("6")
n.right.right.left = tree ("7")
n.right.right.right = tree ("4")

sum = n.determine_sum (0)
print (sum)

Cleric – Does the phrase "Magic Level" of "Disciples of Life" and "Blessed Healer" refer to the slot level or not?

Regarding the following abilities of the cleric life area:

Student of life

Whenever you use a 1st Level or higher spell to restore hit points
For a creature, the creature receives additional hit points equal to 2+
the level of the spell.

Blessed healer

If you cast a 1st Level or higher spell that restores hit points
For a creature other than yourself, you get hit points equal to 2 +
Caster level.

They both refer to "the level of the spell." I understand that even if you cast a 1st-level Healing Word with a 9th-level Spell Slot, "the level of the spell" still returns 1. Is that correct? Or is 9 in my example? If 9 were correct, I would think that the wording should be "equal to 2 + the level of magic slot used".

Regex – Search for a phrase I know only with Google operators

I'm looking for a specific combination of Google hacking commands to find a sentence.
For example, I'm looking for "where dare eagles"
In this case I have no part of a sentence like the following example:

where to dare xxx

I'm sure about the first and last word, but I do not know what's in the middle.
I use

"Where" and "dare"

But it did not work right.

Ranking on Google for specific phrase

Hello,

I have a new company and website (created under WIX). I want my site to appear on a Google search when people search for "spaghetti bridge". It's a pretty specific phrase, but I know these people would be interested in my product. I have a lot of content on my website that contains the phrase Spaghetti Bridge, but I can not get my website to appear. Google only returns 17 result pages, so I think it should not be too difficult to organize organically. But my website does not appear on these 17 pages. Some of the links that appear are not even better than mine.

Any suggestions? I'm still pretty new to SEO, so maybe I'm missing something.

Any help would be really grateful.

Many Thanks,
Joel

bip32 – Why seed of BIP39 mnemonic phrase is much longer than entropy?

This is stated in GDP 39 itself:

To create a mnemonics binary kernel, we use the PBKDF2 function with a mnemonics clause (in UTF-8 NFKD) as the password and the string "mnemonic" + passphrase (again in UTF-8 NFKD) as a salt. The iteration counter is set to 2048 and HMAC-SHA512 is used as a pseudorandom function. The length of the derived key is 512 bits (= 64 bytes).

The seed used is essentially a 512-bit hash of mnemonics, which explains why it is 512 bits long (= 128 nibbles).

The GDP does not explain why they do that, but I would assume that it is useful to know that the seed always has a certain size, no matter how much entropy is actually produced. This means, for example, that the key generation code can be written to always work with 512-bit seeds.

ag.algebraic geometry – Non-compact example in which Putinar's positivity phrase fails

Putinar's positives can be described as follows: A compact set of polynomial inequalities $ mathcal {P} = {P_1 (x) geq 0, ldots, P_m (x) geq 0 } $ is unsatisfactory only if the sum of the polynomials of the squares exists $ Q_0 (x), ldots, Q_m (x) in Sigma ^ 2 $ so that $ -1 = Q_0 + sum_ {i in [m]} Q_i (x) P_i (x) $,
I wondered if an explicit, non-compact set of polynomial inequalities is known, where it is known that the generalization of the Putivi positive-theorem where we drop the compactness requirement fails.
Thanks for your help.
