In python to remove duplicates we use unordered iterable set() but in Go it is not so straight forward, there is no package to do this i think... So here's an example on how duplicate elements are removed. Algorithm A flag variable is created using make(), flag is a map that has a key that … Continue reading [Go]Remove duplicate elements in array/slice
The string is a physical address, then this is split into an array, which then captures the last element of the array. This last element is the actual mac address, then replace all "-" with ":" with the strings package. For converting cisco mac address format, first remove all "-" then slice the strings up, … Continue reading [Go]Replace characters in string.

It is not overly hard but it … Continue reading [Go]Assignment 3: Open a text file and display the content
This is an assignment 2 about interface from the course Go: The Complete Developer's Guide (Golang) by Stephen Grider, this topic is difficult to understand but Stephen explained it well. Below is the code for the assignment2. So the purpose of interface in golang is to try to reduce the code, while golang is not … Continue reading [Go]Interface assignment 2
9Pointer is a variable that stores the memory address/register of the variable. If you extract the pointer variable without the asterix(*) sign, you will only get the register of the variable. In order to get the value you need to de-reference the pointer variable by using the asterix(*).
While array in Go is fixed size, slice on the other hand is not. You declare a variable without specifying the size, and if new element is needed use the append() function to add element to each index.
Array is fixed in size hence it is not flexible, I need to declare the size of the array, and the values cannot exceed the size which I declared.
Go has some similarity with python and a lot are different, fortunately during my university I was forced to take up foundation of programming which I have learned C. So below are the codes which I have put in comments to explain the statements. simplemath package Main package that imports simplemath and runs it
Background web client implementation is within the package net/http, this code uses this package to write an API client. Examples can be found in Golang. This API test website is used for testing the code. The endpoint which the code uses is /posts/1 as the json response is the shortest. Postman This is the response … Continue reading [Go] API client
