The price of bitcoin hit $50,000 today, a month after the U.S. Securities and Exchange Commission approved 11 applications for spot bitcoin ETFs. The issuers of those ETFs have seen demand skyrocket beyond initial predictions of a few billion. Assets under management at these issuers total around $28.35 billion, making for a market cap of $39.8 billion, according to Blockworks data. Trading volume across 24 hours was $1.38 billion. Leading the spot bitcoin ETF pack is Grayscale Bitcoin Trust at $20.27 billion,…

Crypto asset manager Bitwise said on Friday that $240 million flowed into its spot bitcoin exchange-traded fund (ETF), the most of the 10 such products that began trading on Thursday.The U.S. Securities and Exchange Commission approved 11 spot bitcoin ETFs this week, including BlackRock's iShares Bitcoin Trust, Grayscale Bitcoin Trust, and ARK 21Shares Bitcoin ETF, among others, after a decade-long tussle with the digital asset industry. The first day of trading saw $4.6 billion worth of shares trade hands across all the…

Given an integer array arr of size N, the task is to count the number of pairs whose BITWISE AND and BITWISE XOR are equal.Examples:Input: N = 3, arr = Output: 1Explanation: All possible pairs from the array are pair = . we can see that pair = (0, 0), 0&0 == 0 and 0^0 == 0 this pair stratified the given condition so, we increase our answer by += 1for pair = (0, 1), 0&1 == 0 and 0^1 == 1, we can see that these are not equal we can’t increase our ans.we check for last also, in last also they are not equal.So, our…

Given a Singly linked list of integers, the task is to count the number of pairs of nodes whose bitwise AND is a prime number.Examples:Input: 4 -> 2 -> 3 -> 1 -> 5 -> 6Output: 3Explanation: The only pair with bitwise AND being a prime number is (2, 3), (2, 6), (3, 6).Input: 10 -> 3 -> 5 -> 7 -> 2 -> 15Output: 11Explanation: The pairs with bitwise AND being a prime number are (10, 3), (10, 7), (10, 2), (3, 7), (3, 2), (3, 15), (5, 7), (5, 15), (7, 2), (7, 15), (2, 15).Approach: This can be…

We can also get 50 by other integers but 15 is the smallest to give maximum value.Input: A = 10000000, B = 64235678983Output: 64235683719Naive Approach: To solve the problem follow the…

Given an array arr of size N ( N is even ), the task is to construct an array B such that the sum of B XOR PrefixXor, where 1 ≤ i ≤ N is even and is divisible by the first N/2 elements of arr. PrefixXor array is an array where each element will indicate the XOR of all elements from 1st element to the current index element.Examples:Input: N = 4, arr = {2, 6, 1, 5}Output: B = {0, 6, 3, 6}Explanation: Since, prefix array is prefixXor = {2, 4, 5, 0}, (2 ^ 0) + (4 ^ 6) + (5 ^ 3) + (0^6) = 2 + 2 + 6 + 6 = 16, which is even and…
