5 5 5 5 5
4 4 4 4
3 3 3
2 2

Solving in C:

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