Golang Program to Read a Number (n) and Print the Natural Numbers Summation Pattern
Let's suppose the number is: 4
Then, the Summation Patten would be:
1 = 1
1 + 2 = 3
1 + 2 + 3 = 6
1 + 2 + 3 + 4 = 10
Steps
- Take a value from the user and store it in a variable, n.
- Use two for loops where the value of t ranges between the values of 1 and n and the value of i ranges between 1 and t.
- Print the value of i and '+' operator.
- Find the sum of elements in the list.
- Print '=' followed by the total sum.
- Exit.
Example
package main
import "fmt"
func main(){
var n int
fmt.Print("Enter number: ")
fmt.Scanf("%d", &n)
for t:=1; t<=n; t++{
sum := 0
for i:=1; i<=t; i++{
fmt.Printf("%d ", i)
if i < t{
fmt.Printf("+ ")
}
sum += i
}
fmt.Printf("= %d\n", sum)
}
}Output
Enter number: 6 1 = 1 1 + 2 = 3 1 + 2 + 3 = 6 1 + 2 + 3 + 4 = 10 1 + 2 + 3 + 4 + 5 = 15 1 + 2 + 3 + 4 + 5 + 6 = 21
