Actual 2024 Placement Paper Questions

This section contains real questions from Qualcomm placement papers 2024 based on candidate experiences from Reddit, PrepInsta, and IndiaBix.

Coding Questions (2024)

Q1: Two Sum Problem

Problem: Given an array of integers and a target sum, find two numbers that add up to the target.

Example:

Input: nums = [2, 7, 11, 15], target = 9
Output: [0, 1] (because nums[0] + nums[1] = 2 + 7 = 9)

Solution:

def twoSum(nums, target):
    hashmap = {}
    for i, num in enumerate(nums):
        complement = target - num
        if complement in hashmap:
            return [hashmap[complement], i]
        hashmap[num] = i
    return []

Time Complexity: O(n)
Space Complexity: O(n)

Q2: Reverse Linked List

Problem: Reverse a singly linked list.

Solution:

def reverseList(head):
    prev = None
    current = head
    while current:
        next_node = current.next
        current.next = prev
        prev = current
        current = next_node
    return prev

Time Complexity: O(n)
Space Complexity: O(1)

Technical MCQs (2024)

Q1: What is the time complexity of binary search?

Answer: O(log n)

Explanation: Binary search divides the search space in half at each step, resulting in logarithmic time complexity.

Q2: What is the difference between stack and queue?

Answer: Stack follows LIFO (Last In First Out) principle, while Queue follows FIFO (First In First Out) principle.
