C :

#include<stdio.h>
int main()
{
	int i,a,b,c,n,s=0,m=0;
	scanf("%d",&n);
	for(i=100;i<=n;i++)
	{
		a=i/100;
		b=i/10%10;
		c=i%10;
		if((b>a&&c>b)||(a>b&&b>c))
		{
			s+=i;
			m++;
		}
	 } 
	 printf("%d\n%d",s,m);
	 return 0;
 } 

C++ :

#include <iostream>
using namespace std;

int main(){
	int n,g,s,b,i,c = 0,x = 0;
	
	cin>>n;
	for(i = 100;i <= n;i++){
		b = i / 100;
		s = i / 10 % 10;
		g = i % 10;
		if(b < s && s < g || b > s && s > g){
//			cout<<i<<endl;
			c++;
			x += i;
		}
	}
	
	cout<<x<<endl;
	cout<<c<<endl;
}

Java :

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
    	Scanner sc =new Scanner (System.in);
    	int n =sc.nextInt();
    	int k=0,j=0;
    	int a,b,c;
    	for(int i=100;i<=n;i++) {
    		a =i%10;
    		b =i/10%10;
    		c =i/100;
    		if(a>b&&b>c) {
    			k =k+i;
    			j++;
    		}
    		if(a<b&&b<c) {
    			k =k+i;
    			j++;
    		}
    	}
		System.out.println(k);
		System.out.println(j);
    }
}

Python :

n = int(input())
c = 0
su = 0
for i in range(100, n+1):
    bw = i // 100 % 10
    sw = i // 10 % 10
    gw = i // 1 % 10
    if bw < sw < gw or bw > sw > gw:
        su += i
        c += 1
print(su)
print(c)
