Comprehensive Programming and IT Knowledge Quiz with Multiple‑Choice and Coding Questions

The document presents a timed “Programmer Quiz” consisting of single‑choice, short‑answer, and coding questions designed to test a wide range of IT knowledge.

Multiple‑choice items cover famous programming quotes, historical figures such as Ada Lovelace, hexadecimal representations, Java Collection API methods, algorithmic concepts (greedy, backtracking, exhaustive search, divide‑and‑conquer), IPv6 address size, TCP/IP layer ordering, Linux alias usage, Helm chart management, and logical data independence.

The coding section asks candidates to implement file‑copy operations with Python’s shutil module, choose the correct code fragment among four alternatives, and swap two variables using pointers in C, with the relevant snippets shown below.

Python example:

# -*- coding: UTF-8 -*-
import shutil
def test():
    # TODO: implement copy logic
if __name__ == '__main__':
    test()

C pointer‑swap example (option A):

#include <stdio.h>
int main(int argc, char** argv) {
    int x, y;
    int *pt_x, *pt_y;
    x = 2, y = 8;
    pt_x = &x, pt_y = &y;
    printf("Before: x = %d, y = %d\n", x, y);
    int temp = *pt_x;
    *pt_x = *pt_y;
    *pt_y = temp;
    printf("After: x = %d, y = %d\n", x, y);
    return 0;
}

Short‑answer questions ask for personal reflections on a favorite technology, a binary‑tree leaf‑removal algorithm, and the core conflict between programmers and product managers.

Two programming challenges require writing a program to identify “hot posts” that receive at least K likes within any D‑second window, and to count the number of ways to climb a staircase when steps of size 1‑3 are allowed.

The quiz concludes with a motivational note encouraging participants to remember their past scores.
