On Tuesday, India introduced four crew members for its maiden Gaganyaan space voyage, as it aims to become the world's fourth country to send a crewed mission into space, just months after a historic landing on the south pole of the moon.Gaganyaan, or "sky craft" in Hindi, is the first mission of its kind for India and will cost about 90.23 billion rupees ($1.5 billion Cdn). It involves the launch of a habitable space capsule over the next year to an orbit of 400 kilometres, and its return via a landing in the Indian…

It's mating season for coyotes, which means they're more likely to be out and about during the day.With that in mind, the City of Burlington, Ont., is reminding residents what to do if they encounter one, and how to coyote-proof their properties. Last week, the city also updated its bylaws to let wildlife management professionals use firearms but the city's head of bylaw says that's not to make it easier to kill coyotes but makes the response require less staffing."Coyotes have always been here. People just didn't notice…

The world just experienced its hottest January on record, but that wasn't the only new record it set, the European Union's Copernicus Climate Change Service (C3S) said on Thursday.For the first time, the global temperature pushed past the internationally agreed upon warming threshold for an entire 12-month period, with February 2023 to January 2024, running 1.52 C, according to C3S.Last month surpassed the previous warmest January, which occurred in 2020, in C3S's records going back to 1950.Every month since June has been…

Last updated: December 8th, 2023 at 07:03 UTC+01:00 Twitter's (now called ‘X') competitor, Instagram Threads, is developing a new feature called ‘Tags'. Threads Tags work similarly to hashtags, i.e., categorize or group together similar posts and present them alongside the same topic. While this feature of Instagram Threads Tags is similar to hashtags, some functions differ. Unlike hashtags, on Instagram Threads, you can only have a single tag or topic on a post. So, if you are used to using hundreds of hashtags…

Threads — the text-based microblogging platform that competes with X (formerly Twitter) — is testing support for tags, a popular feature on the rival messaging service. Tags function in a similar manner as hashtags on X, but do not include the hash symbol. Meta has also put some limitations on the use of tags on the service. The new tags feature could pave the way for support for trending topics on Threads — another feature that is widely used on X.Instagram Head Adam Mosseri and Meta CEO Mark…

It is commonly used in computer science and computational biology, where it can be used to detect approximate string matches, find repeated substrings, and perform other operations on sequences of data.The idea behind a rolling hash is to compute the hash value for a fixed-size window of data, and then “roll” the window one position at…

They have different storage structures and time complexities, making them suitable for different use cases.

We know about Python dictionaries in a data structure in Python which holds data in the form of key: value pairs. In this article, we will discuss the Bidirectional Hash table or Two-way dictionary in Python. We can say a two-way dictionary can be represented as key ⇐⇒ value. One example of two-way dictionaries is:Example:dict={ 1 : 'Apple' , 2 : 'Google' , 3 : 'Microsoft'} Input 1: 1 Output 1: Apple Input 2: Microsoft Output 2: 3 Explaination:The above dictionary maps…
