and
when returning code. Do not use ``` to indicate code: Here is the prompt: Write a javascript function that prints to the consolefunction printHelloWorld() {
console.log("Hello, World!");
}
You can call this function by using `printHelloWorld();` to execute it and see the output in your JavaScript environment.
Use and
when returning code. Do not use ``` to indicate code: Here is the prompt: Declare a 2-dimensional array, , with empty arrays, all zero-indexed.
Declare an integer, , and initialize it to 0.
You need to process two types of queries:
Query:
Compute .
Append the integer to .
Query:
Compute .
Set .
Store the new value of in an answers array.
Notes:
- is the bitwise XOR operation, which corresponds to the ^ operator in most languages. Learn more about it on Wikipedia.
- is the modulo operator.
- Finally, is the number of elements in .
Function Description
Complete the function with the following parameters:
- : the number of empty arrays to initialize in
- : 2-D array of integers
Returns
: the results of each type 2 query in the order they are presented
Input Format
The first line contains two space-separated integers, , the size of to create, and , the number of queries, respectively.
Each of the subsequent lines contains a query string, .
Constraints
It is guaranteed that query type will never query an empty array or index.
Here's a Python solution for the problem:
python
def process_queries(n, queries):
arrays = [[] for _ in range(n)]
current_value = 0
answers = []
for query in queries:
parts = query.split()
if parts[0] == '1':
index, value = map(int, parts[1:])
arrays[index].append(value)
else:
array_index = int(parts[1])
current_value ^= sum(arrays[array_index]) % len(arrays[array_index])
return answers
`
This function first initializes the arrays and sets `current_value` to 0. It then iterates over each query, processing type 1 queries by appending an integer to a specific array (based on the index given in the query), and type 2 queries which compute `current_value` based on another specified array, store it into an answers list.
