          54321
          4321
          321
          21

Solving in C:

    #include <stdio.h>
    int main(){
        int row,col,count;
        for(row=5;row>=1;row--){
            for(col=1,count=row;col<=row;col++)
               if(row>=col ) printf("%d",count--);
            printf("\n");
        }
        return 0;
    }
