# Go Program to Find Sum of Matrix Upper Triangle

Write a Go Program to Find the Sum of the upper triangle items in a Matrix. In this Go sum of Matrix Upper Triangle example, the nested for loops iterate the matrix row and columns items. Within the loop, the if statement (if j > i) checks whether the column value is greater than the row. If True, add that item value to the matrix upper triangle sum.

```package main

import "fmt"

func main() {
var i, j, rows, columns int

var upTriSumMat [10][10]int

fmt.Print("Enter the Matrix rows and Columns = ")
fmt.Scan(&rows, &columns)

fmt.Println("Enter Matrix Items to find Upper Triangle Sum = ")
for i = 0; i < rows; i++ {
for j = 0; j < columns; j++ {
fmt.Scan(&upTriSumMat[i][j])
}
}
upTriSum := 0
for i = 0; i < rows; i++ {
for j = 0; j < columns; j++ {
if j > i {
upTriSum = upTriSum + upTriSumMat[i][j]
}
}
}
fmt.Println("The Sum of Upper Triangle Matrix Elements  = ", upTriSum)
}```
``````Enter the Matrix rows and Columns = 3 3
Enter Matrix Items to find Upper Triangle Sum =
10 20 30
40 50 90
10 11 44
The Sum of Upper Triangle Matrix Elements  =  140``````

Golang Program to Find the Sum of Upper Triangle items in a Matrix using For loop range.

```package main

import "fmt"

func main() {

var upTriSumMat [3][3]int

fmt.Println("Enter Matrix Items to find Upper Triangle Sum = ")
for i, rows := range upTriSumMat {
for j := range rows {
fmt.Scan(&upTriSumMat[i][j])
}
}
upTriSum := 0
for i, rows := range upTriSumMat {
for j := range rows {
if j > i {
upTriSum = upTriSum + upTriSumMat[i][j]
}
}
}
fmt.Println("The Sum of Upper Triangle Matrix Elements  = ", upTriSum)
}```
