Name: Aivasu Tech Institute
Address: 2nd Floor, Kapil Vihar, Opp. Metro Pillar No.354, Pitampura, New Delhi, Delhi, 110034, IN
Telephone: +91-9667708830
Price range: ₹₹

Difficulty: Lv ★ | Prerequisite Knowledge: Basic Weeks 4-5 + Week 9 (Functions)

Goal

Guess a random number between 1~N — attempt limit + difficulty selection

Differences from Basic Assignment

Basic Week 5 = simple addition Large/Small + number of attempts
Here = attempt limit + difficulty selection + retry option + function separation

Requirements

Select difficulty at the start (Easy 1~~50/7-times, Normal 1~~100/7-times, Hard 1~500/10-times)
Hint + remaining attempts for each try
Reveal answer if attempts exceeded

Input/Output Example

Difficulty (1. Easy 2. Normal 3. Hard): 2
Guess a number from 1 to 100 within 7 tries

[Remaining 7 tries] Number: 50 → Higher number
[Remaining 6 tries] Number: 75 → Lower number
[Remaining 5 tries] Number: 63 → Correct! (3 tries)

One more time? (y/n): n

Challenge Task

User sets the answer and computer tries to guess

Execution
