# What is the proper implementation of building a string representation of the contents of a byte array?

Appending the string builder with the following method is yielding incorrect results. The bytes in the byte array do not match the ‘1’s and ‘0’s represented within the resulting string. InputStream is = new FileInputStream(bout); StringBuilder sb = new StringBuilder(); byte[] a = is.readAllBytes(); for (byte b : a) { for (int i = 0;… Read More What is the proper implementation of building a string representation of the contents of a byte array?

# How to convert one byte and 4 bits from another byte to a short using bitwise?

Using bitwise, how could we convert these 3 bytes to two shorts in this pattern in the most performant way?: (11111111)(01111110)(10000001) 3 bytes (111111110111)(111010000001) 2 shorts Found a way to combine two bytes into a short, but for a combination of 1 byte and 4 bits tried a variety of ways for hours with no… Read More How to convert one byte and 4 bits from another byte to a short using bitwise?

# why I am getting 'NaN' for '&' operator?

I am not able to understand why I am getting this "NaN" while performing AND-Bitwise operator for some numbers only? please see pic I attached to understand My issue clearly. ‘use strict’; function getMaxLessThanK(n, k) { let toknowNum = []; let bitVal = []; let topop = []; if (2 <= n && n <=… Read More why I am getting 'NaN' for '&' operator?

# What does a bitwise AND do with no value infront of it?

I am using Verilog. Say you have the term: & A or ~& A What does this do? Does it just compare it to an all empty array? >Solution : It performs a bitwise operation on all bits of the operand e.g.: //let x = 4’b1010 &x //equivalent to 1 & 0 & 1 &… Read More What does a bitwise AND do with no value infront of it?
