Skyscrapers

$5000$ years later, when the coronavirus epidemic was stopped, $n$ skyscrapers are planned to be built in Baku. We will represent Baku as the coordinate axis of numbers. For each skyscraper, its coordinate (x_i) and height (h_i) are given. Engineers consider the skyscraper unprofitable if to the left of it at a distance of no more than $d$, and also to the right of it at a distance of no more than $d$, there is a skyscraper whose height is at least twice that of the given skyscraper (this skyscraper itself may be unprofitable). Such skyscrapers are considered unsuccessful from a business point of view, so engineers plan to build some other facility instead. You must calculate the number of unprofitable skyscrapers so that engineers can make appropriate decisions.
