For this Question: Tom has been given an integer array A of size N. Now, he needs to find the number of increasing sub-sequences of this array with length ≥1 and GCD=1. A sub-sequence of an array is obtained by deleting some (or none) elements and maintaining the relative order of the rest of the elements. As the answer may be large, print it Modulo (10^9)+7.The first line contains a single integer N denoting the size of array A. The next line contains N space-separated integers denoting the elements of array A.

Constraints:
1 ≤ N ≤ 500
1 ≤ A[i] ≤ 100Print the required answer Modulo 10^9+7.Sample Input

Sample Output
5, I have written this Solution Code: import java.io.*;
import java.util.*;



class Main {
	public static int gcd(int a, int b) {
		if(b == 0) {
			return a;
		}
		return gcd(b, a % b);
	}
	public static long cal(int arr[], int n){
		long dp[][] = new long[n][101];
		for(int i = 0; i < n; i++) {
        dp[i][arr[i]] = 1;
        for(int j = i - 1; j >= 0; j--){
            if (arr[j] < arr[i]){
                for(int k = 0; k <= 100; k++) {
                    int GCD = gcd(arr[i], k);
                    dp[i][GCD] = dp[i][GCD] + dp[j][k];
                }
            }
        }
    }
    long sum = 0;
	int MOD = 1000000007;
    for(int i = 0; i < n; i++) {
        sum = (sum + dp[i][1]) % MOD;
    }
    return sum;
	}
	public static void main (String[] args) throws IOException{

		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
		String nD = br.readLine();
		String nDArr[] = nD.split(" ");
		int n = Integer.parseInt(nDArr[0]);
		int arr[]= new int[n];
		String input = br.readLine();
		String sar[] = input.split(" ");
		for(int i = 0; i < n; i++){
			arr[i] = Integer.parseInt(sar[i]);
		}
		System.out.println(cal(arr, n));
}
}, In this Programming Language: Java, Now tell me if this Code is compilable or not?
