The blockchain, as a distributed ledger technology, is purposefully built to be very resistant to tampering and fraud (such as double-spending). This is because the Bitcoin blockchain, as a database of records, cannot be changed or tampered with without an impractical amount of electricity and computational power, meaning the network can enforce the concept of "original" digital documents, making each Bitcoin a very unique and uncopyable form of digital currency. One of the significances of blockchain technology is increased security. The term "blockchain" comes from the way the technology works: it may generate an unalterable record of transactions using end-to-end ... Read More
We are given a string and an integer k, and we need to reorder the characters in the string so that it becomes the concatenation of k similar substring. If not possible, output the result as "Impossible”. string = "malaalam"; K = 2; res = solve(s, K); Example (Using Maps) Let's have a string "mottom" and K=2. The given string can be represented as the concatenation of 2 substrings like tomtom, motmot omtomt, etc. As in all 3, two substrings are joined together when k = 2. Using the string, we can determine how many times each character occurs. ... Read More

Financial transactions and trading operations are critical components of a global or national economy. The global economic system manages trillions of dollars in transactions while servicing billions of clients. Because beneficiary intermediaries are involved in the transactional process, both parties must pay a transaction fee. The introduction of blockchain technology proved advantageous in carrying out such transactions without middlemen. Blockchain creates a digital transaction ledger in which all digital transactions are recorded. Exploring new technologies is motivated by the need to do activities more quickly and inexpensively. Furthermore, the present digitalization trend is forcing organizations to keep up and integrate ... Read More
A series of integers is given in this article. Let's say we have an array of four elements without counting the repetitive elements, [2, 2, 5, 5, 7, 8, 7], and we have to make the array distinctive. Changing a value with one that is greater than the previous one is possible. In the above array, element 2 at index 1 becomes 3 as the next greater element. 5 at index 3 becomes 6 as the next greater and so on. So, in the end, our array becomes [2 3 5 6 7 8 9] and should minimize the sum ... Read More
The internet, with all of its accouterments, is meant to bring new efficiency to the environment. The option to send an email instead of a letter helps the environment. Video conferencing decreases carbon emissions by allowing people to connect face-to-face without having to travel by car or plane. Big data is supporting and will continue to support an economy that is considerably more efficient than ever before, as well as identifying innovative solutions that allow for long-term development. Due to its ability to decentralize data and operations while still assuring top-tier security, blockchain plays a significant role in these advancements. ... Read More
