First question The integer array nums is arranged in ascending order, and the values in the array are different from each other. Before passing to the function, Num rotates on a previously unknown subscript k (0 < = k < num.length), making the array [num [k], Num [K + 1],..., Num [n-1], Num [0], Num [1],..., Num [k-1]] (subscripts count ...

1. Title: Let X[0:n-1] and Y[0:n-1] be two arrays, and each array contains n ordered numbers. Try to design an O(logn) time divide and conquer algorithm to find the median of 2n numbers of X and y. Algorithm idea: In fact, we don't need to really merge the two arrays. We just need to find out where the median is. The initial idea is to writ ...

1.Hash related When using HashMap, why can you find the corresponding value according to map.get(key) with time complexity O(1)? Because the physical structure uses a hash table Calculate the array position where the Entry should be stored according to a special algorithm. If the positions are the same, there are various methods to solve the ...
