Read MoreGolang program that takes in a list of weights and values for items and a maximum weight capacity for knapsack
In this Go language article, we will write programs that take in list of weights and values for items and a maximum weight capacity for knapsack. Knapsack problem is an optimization problem that uses dynamic programming. Here, the purpose is to find out the set of items that can be included in the knapsack without exceeding its weight capacity or maximum weight. Dynamic programming involves solving of problems by breaking them down into smaller subproblems and them combining them to get an optimal solution. Syntax func make ([] type, size, capacity) The make function in go language ...
Read MoreGolang program that takes in a slice of integers and an anonymous function that filters each element in the slice
In this Go language article, we will write programs that take in a slice of integers and an anonymous function that filters each element in the slice. An anonymous function is the function which uses no function name and is called by the variable which is assigned to it. It is used generally used with event listeners. Here, Filter function will be created with the anonymous functions to filter the values from slice. Syntax func append(slice, element_1, element_2…, element_N) []T The append function is used to add values to an array slice. It takes number of arguments. The first ...
Read MoreGolang program to print the numbers 1 to 100 concurrently, with each number printed by a separate goroutine
In this article, we will write a Go language program to print the numbers from 1 to 100 concurrently with each number printed by a separate go routine. Concurrency means execution of multiple tasks parallelly and independently and making sure all the resources of the system are utilized. It can be achieved via go routines which are light weight threads and the channels. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments. Algorithm ...
Read MoreGolang program to take in a slice of integers and compute their sum using concurrency
In this Go language article, we will write programs to take in a slice of integers and compute their sum using concurrency. Concurrency helps multiple tasks or operations to be performed simultaneously. It helps make efficient use of system resources. It is achieved using Go routines which are light-weight threads and channels which helps in the communication between the go routines. Syntax func make ([] type, size, capacity) The make function in go language is used to create an array/map it accepts the type of variable to be created, its size and capacity as arguments. func range(variable) The ...
