Clinic #19 - Kth Largest Element in an Array

Pattern: Heap (size-k) · LC 215

Ek chhota sa board, jismein numbers ek arrangement mein pin hote jaate hain, top-5 wale notice-board jaisa, aur upar wali jagah hamesha sabse chhoti value rakhti hai. Yehi ulta trick is lesson ka core hai.

Before you start. Bas itna pata ho ki array numbers ki list hai, har number ki apni jagah (index) hoti hai, aur sort karna matlab chhote se bade order mein lagana. Baaki jo naya lagega - heap, root, Big-O - lesson ke andar hi dikhaya jayega.
