How to print Pascal's Triangle Pattern in Go - Step by Step Examples

How to print Pascal's Triangle Pattern in Go ?

Answer

To print Pascal's Triangle Pattern in Go, you can use nested loops where the outer loop controls the rows and the inner loop calculates the values for each row based on the binomial coefficient formula.

✐ Examples

1 Pascal's Triangle Pattern

In this example,

We use a variable n to represent the number of rows in Pascal's triangle.
We initialize a 2D array pascal to store the triangle values.
We use nested loops to calculate and store the values using the binomial coefficient formula.
We print the triangle values using a formatted output.

Go Program

package main
import "fmt"

func printPascalsTriangle(n int) {
    pascal := make([][]int, n)
    for i := range pascal {
        pascal[i] = make([]int, i+1)
        for j := range pascal[i] {
            if j == 0 || j == i {
                pascal[i][j] = 1
            } else {
                pascal[i][j] = pascal[i-1][j-1] + pascal[i-1][j]
            }
            fmt.Printf("%d ", pascal[i][j])
        }
        fmt.Println()
    }
}

func main() {
    rows := 5
    printPascalsTriangle(rows)
}

Output
