Agar aap Python programming seekh rahe hain ya kisi technical interview ki tayari kar rahe hain, to aapko sirf syntax ya libraries hi nahi, balki problem-solving skills bhi strong honi chahiye. Isliye aaj ka sawaal simple lagne ke bawajood kaafi powerful hai.
🧠 Is practice question ka focus hai string manipulation aur hashing technique par. Aapko ek aisi logic design karni hai jisme aap first non-repeating character ko efficiently identify kar saken. Ye concept real-life situations mein bhi kaam aata hai — jaise log files mein unique errors dhoondhna ya user input validate karna.
Is type ke sawaal commonly Python interviews mein pooche jaate hain, especially jab interviewer aapki understanding test karta hai:
Data Structures jaise dictionary ka use
Time complexity ka analysis (O(n) vs O(n²))
Clean aur readable code logic
Interview mein interviewer aapse yeh nahi poochega ki "function kaunsi library se hai", wo dekhega ki aap real problem ko kaise approach karte ho — clarity, optimization aur explanation ke saath.
