How are floating-point numbers stored in a computer? Computers represent all information in binary. Floating-point numbers are also converted to binary and stored in RAM, but during this process, some of the value is lost, resulting in an approximation rather than the exact value.  For example, when you convert 0.1 to binary, it becomes a repeating decimal: 0.00011001100110011... which continues..

Three Methods to Reverse a List [::-1] This method reverses the list by slicing it in reverse order. It creates a new list, so if the list is very large, it can lead to unnecessary memory usage. reverse() This method directly reverses the original list, which means it uses less memory. However, since it modifies the original list, it should not be used if you want to keep the original list intac..

All processes are carried out by opening the terminal and entering Git commands.

sys.stdin.readline() returns an empty string!import syswhile True: try: userInput = sys.stdin.readline().strip() print(userInput) except: break EOFError(End of File) means the end of the file, or the end of input. The input() function raises an EOFError at the end of the file, but sys.stdin.readline() returns an empty str, so it does not raise an EOFError. This can lea..

For each letter of the alphabet, output the position of its first occurrence in the word if it is present; if it is not present, output -1. Input The first line contains the word S. The length of the word does not exceed 100, and it consists only of lowercase letters.baekjoon Output For each letter of the alphabet, output the pos..

For empty list generation Even if you plan to add a value to a list, you need to initialize that list beforehand for the program to function correctly. In Python, an empty list is created by entering "[]". The two codes below are examples of how I initialized a list while solving problems on BOJ.# https://www.acmicpc.net/problem/10871import sysN, X = map(int, sys.stdin.readline().split())A = lis..
