Today we continue reviewing Bing Maps API

These APIs include map control and services that can be used to make maps part of your application. These APIs are an authoritative source for geospatial features. They offer static and interactive maps, geocoding, route and traffic data.Any spatial data such as store locations can be queried and stored with these APIs. Typically an account and a key is needed to use the APIs. The key is used as a license to utilize their services. They are classified as used for public website, private website and enterprise assets.

The Bing Maps dev center provides account management functionality. An account is needed to cut a key and to manage data sources.

The Bing Maps Services include REST services and spatial data services. The REST services provide geocoding, routing, elevation, imagery etc. and traffic incident information. The data services provide batch geocoding and spatial data source query and management.

The Web controls available by Bing Maps include support for both WPF and native libraries for Android and perhaps iOS. The geocoding API helps geocode a large batch of addresses. The FindBy APIs help with the querying.

The REST services automatically come  with transaction accounting that helps determine billable and non-billable transactions.

The API options from Bing Maps platform can be listed as follows: 

1) The V8 Web Control: This is one of the most universal mapping control available on Bing Maps platform with support for almost every type of browser and web application.

2) The Windows 10 universal platform that helps us build map apps for a variety of windows devices

3) The Windows Presentation Foundation that enables rich user experience on desktop applications including touch controls

4) The REST based services that facilitate tasks such as geocoding, reverse geocoding, routing and static imagery

5) The spatial data services that offer three key functionalities batch geocoding, point of interest data and the ability to store and expose spatial data. Imagine the geographical data columns added to almost all points of interest on the world map.

6) The developer resources such as documentation on APIs and SDKs.

Given a range [L,R] find the count of numbers having prime number of set bits in their binary representation. 

Solution:

Initialize an array of prime numbers we can use as divisors against the count of set bits

Iterate through the elements from L to R inclusive

count the bits for others and use the divisors
Since the numbers are contiguous, we can use the previous count and positions to determine current count as the counts typically wrap around in small ranges.
