Coding Problems

Practice2 questions

Question 1

Continuous Character Pairs

Problem

Write a program to print the given string S in continuous character pairs. For instance, "testing" should be printed as "te st in g". Read the input from STDIN and print the output to STDOUT. Do not write arbitrary strings anywhere in the program, as these contribute to the standard output, and test cases will fail.

Constraints: S is a single word.

Input Format: Single line of input contains S, a string.

Output Format: The output must display the character pairs of the given string S. If the string has an odd length, then print the last character as it is.

Example:

Input: Indian
Output: In di an

The character pairs are In, di, and an.

Question 2

Sum and Product of Highest and Lowest Elements

Problem

Given an array of size M of positive integers, write a program to find the sum S and the product P of the highest and lowest elements of the array Arr. Read the input from STDIN and write the output to STDOUT. Do not write arbitrary strings while reading the input or while printing, as these contribute to the standard output, and test cases will fail.

Constraints: Array size M > 2. Array elements are unique and greater than 0.

Input Format: The first line contains M, the size of the array. The second line contains M elements separated by a single space.

Output Format: The first line contains the sum S. The second line contains the product P.

Example:

Input:
5
12 1236 45 67 1
Output:
1237
1236

Maximum element = 1236 and minimum element = 1, so S = 1236 + 1 = 1237 and P = 1236 * 1 = 1236.

Example 2:

Input:
13
5 3 6 8 4 26 2 9 11 12 13 15 16
Output:
28
52

Maximum element = 26 and minimum element = 2, so S = 28 and P = 52.

Question 1

Prompt Writing - Suspicious Login

Problem

A user receives a notification that their company account was accessed from an unfamiliar location or device.

Write a prompt that you would give to an AI assistant to help investigate why this computer is not getting a wired network connection and recommend appropriate troubleshooting steps. Submit only the prompt.

Question 1

AI Fluency - Learning Paradigm

Problem

A telecom company wants to segment its customers based on usage behavior to offer personalized plans. No predefined labels exist. Which learning paradigm applies?

a) Reinforcement Learning
b) Semi-Supervised Learning
c) Supervised Learning

Question 2

AI Fluency - Cosine Similarity

Problem

A team compares cosine similarity and Euclidean distance for embeddings whose norms vary significantly. Why might cosine similarity be preferred for some text embeddings?
