【LRU Cache】Design and implement a data structure for Least Recently Used (LRU) cache. It should support the following operations: get and put. get(key) - Get the value (will always be positive) of the key if the key exists in the cache, otherwise return -1. put(key, value) - Set...
linked lists are very slow when searching for an item at a particular index. An array, by comparison, has quickgets when searching for an index, but a linked list must start at the beginning, often called the "head", and loop through each item'snext...

for each child node c of source { dfs(c); } mark source.finish = time++; } Each time you mark a finish time, you can put it into the head of a linked list (the linked list will be sorted from the latest finish time to the earliest finish time). and the linked list will be ...
The astute may have realized that we could express the number of operations as: n2 + 2n. But as you saw from our example with two numbers of a million digits apiece, the second term (2n) becomes insignificant (accounting for 0.0002% of the total operations by that stage). One can ...

The merge algorithm compares the first element of both lists at each step, removes the smaller one from one of the lists, and appends it to the resulting list — after each step, the total size decreases by 1. Therefore: No. of operations required to empty both lists = sum of sizes of...
They also perform a series of computations to search for a global optimal solution in the solution space. As the name suggests, genetic algorithms use techniques inspired by operations found in evolutionary biology such as selection, crossover, and mutation. Genetic algorithms are different from ...
