Flipping bits
Problem Statement :
You will be given a list of 32 bit unsigned integers. Flip all the bits (1->0 and 0->1) and return the result as an unsigned integer. Example n=9(10) 9(10)=1001(2). We're working with 32 bits, so: 000000000000000000000000000001001 = 9(10) 111111111111111111111111111110110 = 4294967286(10) Return 4294967286. Function Description Complete the flippingBits function in the editor below. flippingBits has the following parameter(s): int n: an integer Returns int: the unsigned decimal integer result Input Format The first line of the input contains q, the number of queries. Each of the next q lines contain an integer, n, to process. Constraints 1 <= q <= 100 0 <= n < 2^32

Solution in C :
In C++ :
#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;
typedef long long ll;
ll val = 4294967295L;

return 0;
}
In Java :
import java.util.Scanner;
public class Solution {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int T = scanner.nextInt();
long mask = (1L << 32) - 1;
for (int t = 0; t < T; t++) {
long n = scanner.nextLong();
System.out.println(n ^ mask);
}
scanner.close();
}
}
In C :
#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
int main() {
int t;
unsigned int n;
scanf("%d", &t);
while(t-- > 0) {
scanf("%u", &n);
printf("%u\n", ~n);
}
return 0;
}
In Python3 :
T = int(input())
for _ in range(T) :
N = int(input())
print(0xffffffff & ~N)

You are a waiter at a party. There is a pile of numbered plates. Create an empty answers array. At each iteration, i, remove each plate from the top of the stack in order. Determine if the number on the plate is evenly divisible ith the prime number. If it is, stack it in pile Bi. Otherwise, stack it in stack Ai. Store the values Bi in from top to bottom in answers. In the next iteration, do the

A queue is an abstract data type that maintains the order in which elements were added to it, allowing the oldest elements to be removed from the front and new elements to be added to the rear. This is called a First-In-First-Out (FIFO) data structure because the first element added to the queue (i.e., the one that has been waiting the longest) is always the first one to be removed. A basic que

You are given Q queries. Each query consists of a single number N. You can perform any of the 2 operations N on in each move: 1: If we take 2 integers a and b where , N = a * b , then we can change N = max( a, b ) 2: Decrease the value of N by 1. Determine the minimum number of moves required to reduce the value of N to 0. Input Format The first line contains the integer Q.
