Background: The process of switching curtains, so that the environment between light and dark overBake a light, dark two lighting map beforehand. Then the code is implemented, and the curtain switch is implemented by the action, and the code is over

Algorithm idea: The basic idea is the divide-and-conquer algorithm, that is, a problem is divided into a number of smaller parts of the recursive solution. The specific to the merge sort is to divide the ordered sequence into small sequences,

Basic idea: A precondition of dichotomy is that the sequence is already ordered, and then the value to be looked up is compared to the midpoint of the sequence. Based on the comparison results, select the part to compare next. Binary search is the

Algorithm thought: A[i] The procedure to insert into a sorted a[0,1,2,... i-1] is to compare a[i] with the sorted elements, find where it should be inserted, and move the subsequent element back one bit.Cycle this process to complete sorting⒈
