Time Complexity

What is time complexity ? Ans: Time complexity not a run time of a code, its totally depends on system configuration, processor, server , input size will increase time complexity. Time complexity ko likhne ke tarike jo hote hai use notation kehte hai. Notation is basically symbol NOTATION OF COMPLEXITY Best Case: kam se kam time me chla gya code best case hota hai Ω (Omega) Ω(1) se likhte hai Average Case: Ek average time jisme code chle  Θ(n+1)/2 Worst Case: Worst case ka mtlb kuch bhi ho jaye is time ko ye exceed nhi kregea O(n) Nested Loop me Time Complexity multiply hoti hai aur n^2 banti hai Wahi Do different loops me N+M hoti hai jisme jiski sabse bdi value hai wo big of O me jati hai O(1) - Constant Time: Operations that take a constant amount of time, regardless of the size of the input data. O(log n) - Logarithmic Time: Algorithms that have a logarithmic time complexity, often seen in binary search or certain tree-based algorithms. This is best time Complexity this i...
