Nodes in a binary search tree that span a range

I have a binary search tree of height $ h$ with an integer in each leaf. I also have a range $ [\ell,u]$ . I want to find a set of nodes that span the range $ [\ell,u]$ , i.e., a set $ S$ of nodes such that the leaves under $ S$ form all (and only) those leaves containing integers in the range $ [\ell,u]$ . How large does $ S$ need to be, in the worst case, as a function of the height $ h$ ? How do I find such a set explicitly?

Scroll google calendar month view one week at a time, to span 2 months partially – “vertical scrolling”?

Since years, I’m annoyed when trying to scroll in month view. It always jumps to the beginning of the next month. This feels really bad and sometimes makes it hard to visualize and understand how several events are arranged in relation to each other (or to today)… Hard to describe 🙂

I know, there is a custom 2, 3 or 4 week setting, where you can have a view across a month border. It could be nice, but it still doesn’t scroll by a week.

Today I wanted to drag-and-drop multiple events from June 30th to somewhere in July – First I couldn’t, because even my 3-week-view happened to have the border at the same spot… I modified the settings to get the 2-week-view and was lucky (50% chance) – there I could see the 2 weeks I wanted on the same screen.

How can I align span text with text in other columns?

I have a row with six columns of image and text here:

I want to align the two-line text (e.g. Resources and Reserves) with “Exploration” and “Geological Data”.

Adding a margin below the image doesn’t do the trick, nor does adding a margin above the text… also tried setting a min-height for the icon, but that doesn’t do it either.

How can I accomplish this?

A question about the span of a sequence of polynomials satisfying a linear recurrence

Let F be a finite field and A(n) in F[t], n in N, be defined by a linear recurrence with coefficients in F[t], together with initial conditions. Is there a decision procedure for determining whether the A(n) span F[t] over F? — Example 1: F=Z/2. $ A(n+6)= t^6A(n) + tA(n+1) + t^4A(n+2) + t^2A(n+4)$ . The initial values are: $ A(0) = A(1) = A(2) = A(3) = A(4) = 0$ , $ A(5) = 1$ .

— Example 2: F=Z/2. $ A(n+4)=t^4A(n) + t^2A(n+1) + tA(n+2)$ . Initial values: $ A(0) = A(1) =0, A(2) = 1, A(3) = t$ .

Example 1 arises from the theory of level 1 elliptic modular forms over Z/2. The A(n) do span–there is a proof using the theory of the Hecke operator T5 on this space of forms, due to Nicolas and Serre, which involves a lot of messy computation as well. (There’s also an elementary not as messy proof I’ve concocted).

My guess is that the A(n) of the ad hoc Example 2 span as well, even though there is no underlying Hecke theory. But I’ve no idea how to handle such questions in general. To illustrate the difficulties note that in Example 2, the smallest n such that $ t^{43}$ is a sum of A(k) with k at most n is 2192. And the smallest n such that $ t^{107}$ is a sum of A(k) with k at most n is 3989.

Como inserir elementos HTML span em objecto react?

Esse é o código

import React, {Component} from 'react';  const content = {   title: `Cl<span className="mask">i</span>entes`,   description: 'Veja abaixo nossos clientes!' }  export default class Hero extends React.Component {      render() {         return (             <div id="hero">               { => (                 <div class="hero-content">                     <div class="hero-header">                         <h1>{item.title}</h1>                         <h2>{item.description}</h2>                     </div>                 </div>                 ))};             </div>         );     } }

Is a linearly independent set whose span is dense a Schauder basis?

If $ X$ is a Banach space, then a Schauder basis of $ X$ is a subset $ B$ of $ X$ such that every element of $ X$ can be written uniquely as an infinite linear combination of elements of $ B$ . My question is, if $ A$ is a linearly independent subset of $ X$ such that the closure of the span of $ A$ equals $ X$ , then is $ A$ necessarily a Schauder basis of $ X$ ?

If not, does anyone know of any counterexamples?

¿como puedo hacer para que el resultado de prima neta que es un span me aparezca dentro del input?

En el script lo tengo asignado por defecto la cuota base y el iva ¿Como le puedo hacer para que me deje poner en el input la cuota base y en el iba me muestre el 16% del resultado de la prima neta que en este caso seria 480?

En el total ¿Como le hago para que no me salgan con tantas decimales?

Probability of non-nesting perfect matching on N-path with given span?

Given a path graph $ P_n$ ($ n$ is even). We add new set of $ n/2$ edges $ C$ between non-adjacent path nodes such that set $ C$ forms a perfect matching. The output graph is the union of path $ P_n$ and perfect matching $ C$ . Each edge $ e$ connects two non-adjacent nodes $ V_i$ and $ V_j$ on the path $ P_n$ . The span of an edge $ e(i,j)$ in perfect matching equals $ abs(i-j)$ . The span of perfect matching $ C$ is $ \max_{ e \in C } span(e)$ .

What is the probability of existence of non-nesting perfect matching when perfect matching’s span is at most $ n^r$ where $ r \lt 1$ ?

This was motivated by this post.
