Python Network Programming I - Basic Server / Client : B File Transfer Python Network Programming II - Chat Server / Client Python Network Programming III - Echo Server using socketserver network framework Python Network Programming IV - Asynchronous Request Handling : ThreadingMixIn and ForkingMixIn Python Interview Questions I Permutations I & II Leetcode Solution | Python Leetcode Solution Python Program Profile: https://mohdtalha.netlify.app/ Blog: https://bit.ly/2XHeMBj The video is the second video in the series of CAT based Permutations and Combinations. We have two consecutive integers k1 and k2, k2 = k1 + 1 We need to calculate the lowest integer n, such that: the values nk1 and nk2 have the same digits but in different order. To generate all the permutations of an array from index l to r, fix an element at index l and recur for the index l+1 to r. Backtrack and fix another element at index l and recur for index l+1 to r. Repeat the above steps to generate all the permutations. For example: Given "25525511135", return ["255.255.11.135", "255.255.111.35"]. Never . Valid Palindrome. That removes all duplicate values, since they will hash to the same thing. Afterwards you can return the list() of unique permutations. Example: Input: [1,1,2] Output:[[1,1,2], [1,2,1], [2,1,1]] Python practice 52: Permutations; Python practice 53: Anagrams; Python practice 54: Pow(x, n) Python practice 55: Maximum Subarray; Python practice 56: Jump Game; Python practice 57: Spiral Matrix II; Python practice 58: Rotate List; Python practice 59: Unique Paths II; Python practice 5: Remove Element; Python practice 60: Minimum Path Sum Reading time ~2 minutes Problem is here Solution.
