Number patterns

pattern 1 can be printed like this..you can follow the same method to output pattern 2

while(no_of_rows) {
    while(no_of_columns) {
        calc no. of columns of spaces
        while(no_of_columns_for_spaces) {
            print spaces
            decrement no_of_columns_for_spaces
        }
        calc no. of columns of numbers
        while(no_of_columns_for_numbers) {
            print numbers
            decrement no_of_columns_for_numbers
        }
        decrement no_of_columns
    }
    decrement no_of_rows
}
