What this article shares to you is about how to print out the hourglass in Go language. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article.

Answer to the question

Print hourglass (20 points) Go language | Golang

You are required to write a program to print the given symbol into the shape of an hourglass. For example, given 17 "*", print is required in the following format

*****

***

*

***

*****

The so-called "hourglass shape" means that each line outputs an odd number of symbols; the center of each line is aligned; the number of symbols between the two adjacent lines is 2; the number of symbols decreases from large to small to 1, and then increases from small to large; the number of symbols at the beginning and tail is equal.

Given any N symbols, it may not exactly make up an hourglass. Require the printed hourglass to use as many symbols as possible.

Input format:

The input gives a positive integer N (≤ 1000) and a symbol on one line, separated by a space.

Output format:

First print out the largest hourglass shape made up of a given symbol, and finally output the number of unused symbols in one line.

Enter a sample:

19 *

There is no blank line at the end

Sample output:

*****

***

*

*****

two

There is no blank line at the end

Train of thought

The basic output, if you think this question is unfriendly, you can skip it and do it later to understand it.

Is to find the rules and first figure out how much is needed. Then subtract and get the remaining quantity. Then print the hourglass according to the rule, which is actually an arithmetic sequence.

The code is as follows: package mainimport ("fmt") func main () {var n int var tag byte var sum, nextSum int _, _ = fmt.Scanf ("d% c", & n & tag) sum = 1 nextSum = 1 I: = 1 last: = 0 for true {/ / first calculate the symbol I + = 2 nextSum + = I * 2 if nextSum = 1 J=j-2 {/ / first print the top half var space = (I-j) / 2 for k for
