प्रस्ताव
एंटी-एक्सएसएस ब्राउज़र एक्सटेंशन स्थापित करने के बाद, स्टैक स्निपेट्स ने अचानक स्टैक एक्सचेंज नेटवर्क पर काम करना बंद कर दिया। मैं अब स्टैक ओवरफ्लो से सीख नहीं सकता था , उपयोगकर्ता अनुभव पर काम कर रहे डेमो देखें और, सबसे खराब, प्रोग्रामिंग पहेलियाँ और कोड गोल्फ पर जावास्क्रिप्ट जवाब का परीक्षण नहीं कर सका ! सख्त तौर पर मैंने एक उपाय खोजा, और सेटिंग्स में एक छोटा इनपुट बॉक्स मिला, जिसमें एक एकल रेगेक्स रखा जा सकता था। मैं इस एक, छोटे बॉक्स में स्टैक एक्सचेंज साइटों के सभी फिट नहीं कर सका, इसलिए मैंने मदद मांगी। यह वह सवाल है।
कार्य
आपका कार्य एक नियमित अभिव्यक्ति बनाना है जो स्टैक एक्सचेंज वेबसाइट के सभी URL से मेल खाती है, बिना किसी डोमेन के मिलान के जो कि Stackflow के स्वामित्व में नहीं है।
आपकी नियमित अभिव्यक्ति निम्नलिखित भागों के साथ सभी URL से मेल खाना चाहिए:

यह एक कोड-गोल्फ चुनौती है, इसलिए सबसे छोटी नियमित अभिव्यक्ति जीत जाती है!
