Go Program to Check Sparse Matrix

Write a Go program to check whether the given matrix is sparse or not. Any matrix is a sparse matrix if it contains a large number of zeros. The mathematical formula for Golang sparse matrix is the number of zeros > (m * n)/2.

Within the nested for loop, we used the if statement (if sparseMat[i][j] == 0) to count the total number of zeros in a matrix. The last If else statement (if count > ((i * j) / 2)) checks other the total zeros are greater than the row * columns/2. If True, it is a sparse matrix.

package main

import "fmt"

func main() {
    var num, i, j int

    var sparseMat [10][10]int

    fmt.Print("Enter the Sparse Matrix Size = ")
    fmt.Scan(&num)

    fmt.Print("Enter the Sparse Matrix Items = ")
    for i = 0; i < num; i++ {
        for j = 0; j < num; j++ {
            fmt.Scan(&sparseMat[i][j])
        }
    }
    count := 0
    for i = 0; i < num; i++ {
        for j = 0; j < num; j++ {
            if sparseMat[i][j] == 0 {
                count++
            }
        }
    }
    if count > ((i * j) / 2) {
        fmt.Println("It is a Sparse Matrix")
    } else {
        fmt.Println("It is Not a Sparse Matrix")
    }
}
