Understanding uint8_t in C++
uint8_t is an integer type with a width of exactly 8 bits. In signed types, negative values are represented using 2’s complement without any padding bits.
Meaning of Python’s mean()
In Python, mean() returns the average value of a dataset by dividing the sum of data by the number of data points.
Python Slice with Default Values
In Python, when using slice with missing start or stop index, default values are taken. If step is not defined, it defaults to 1, meaning it goes through each index.
Difference Between cin and cout
cin is used for input streams like files or console, while cout is used for output. They serve as input and output statements, respectively, using different operators.
