[Solved] What are the techniques of Compression? [closed]

[ad_1] Maybe the simplest lossless one is Run-length encoding the string: WWWWWWWWWWWWBWWWWWWWWWWWWBBBWWWWWWWWWWWWWWWWWWWWWWWWBWWWWWWWWWWWWWW will be encoded to: 12W1B12W3B24W1B14W or: WW12BWW12BB3WW24BWW14 And the simplest lossy encoding algorithm would be something like: down-sampling, or averaging over 3 neighbors cells of a vector and keep the average value. 1 [ad_2] solved What are the techniques of Compression?

[Solved] computing hashValue of a file

[ad_1] The problem is you declare resultstream as CHAR resultstream[33]; but then you use in your code resultstream[33] = ‘\0’; The resultstream array is 0 indexed so valid values are 0-32, you are accessing memory not allocated for that array (hence the “Access violation”) 0 [ad_2] solved computing hashValue of a file

[Solved] Asking for an integer [closed]

[ad_1] When you’re using Scanner.nextInt() the input is expected to be an integer. Inputting anything else, including a real number, will throw an InputMismatchException. To make sure invalid input doesn’t stop your program, use a try/catch to handle the exception: int num; try { num = sc.nextInt(); // Continue doing things with num } catch … Read more

[Solved] JavaScript: Convert array of objects into array of object of array of object

[ad_1] You can do something like this const data = [{date: 2021,name: ‘New York’,price: 452}, {date: 2020,name: ‘New York’,price: 452}, {date: 2021,name: ‘Oregon’,price: 452}] const result = Object.values(data.reduce((res, {name,…rest}) => { return { …res, [name]: { name, values: […(res[name] || {values: []}).values, rest] } } }, [])) console.log(result) [ad_2] solved JavaScript: Convert array of objects … Read more

[Solved] How do I print different random numbers in for loop?

[ad_1] You generate the CC number once and display it multiple times. Instead, put the CC generator in the loop. from random import choices from string import digits for _ in range(5): cc_digits = choices(digits, k=16) cc_number = “”.join(cc_digits) space = ” “.join(cc_number[i:i+4] for i in range(0, len(cc_number), 4)) print(space) 1 [ad_2] solved How do … Read more

[Solved] How do websites like cryptocompare.com, coinmarketcap.com or livecoinwatch.com track the prices of cryptocurrencies? What are their sources? [closed]

[ad_1] First you have to understand what the price of something is. The real price of something is how much people are willing to pay for it. If the seller is willing to sell at the price the buyer is willing to buy then a sale happens – the sale also defines the price of … Read more

[Solved] what does ^= mean in js [duplicate]

[ad_1] Bitwise XOR assignment (^=) The bitwise XOR assignment operator (^=) uses the binary representation of both operands, does a bitwise XOR operation on them and assigns the result to the variable. Source: MDN 1 [ad_2] solved what does ^= mean in js [duplicate]

[Solved] Is ARM’s RISC instruction set a subset of x86? If so, why can’t x86 run ARM software natively then?

[ad_1] No, its no. The ARM instruction set may be more limited compared to the x86 instruction set but this has nothing to do with the architecture of the processors. The ARM instruction set is not a subset of x86 instructions. They are encoded differently and the processor executes them in a different way. The … Read more
