[index] >value) {End = index-1; } else { start = index+1; } } return number; }The binary lookup premise is that the array is already ordered. The first index is written as end and start subtraction, resulting in a dead loop. Actually want to be added. 1,2,3,6,7. index=2,value=7,3 is less than 7,start=3, then index wants the middle number between 3 and 4, so it is added and divided by 2,6 less than 7,start=4,find to 7.

quotes is a string value; AI (1〈=i〈=n) can be a letter, a number, or another character; the number of characters in a string is the length of the string. A string of zero length is called an empty string, and it does not contain any characters. Storage mode: ① Sequential storage: A set of contiguous storage units to store string-valued character sequences. ② Chained storage: Each node can store a single character, or can store more than one character, this time to consider the storage

One, what is the stack. As a data structure, the stack is a special linear table that can only be inserted and deleted at one end. It stores the data according to the advanced principle, the first data is pressed into the bottom of the stack, the final data is on the top of

One, what is the direct insertion sort: The first one compares the top two numbers, the second number is then inserted into an ordered table by size; The second one scans the third data with the first two digits, inserting the third number into an ordered table by size, and then, in turn, completes the entire sorting process after the (n-1) scan. In simple terms, the array to be sorted is divided into ordered and unordered groups. Assuming that the ar
