The answer
Calculate the total number of elements mathematically (N * (N + 1) / 2), initialize the external variable to that maximum number, and decrement it on every print.

More FAQs in Floyd's Triangle: Printing Sequential Numbers
Floyd's Triangle is a right-angled triangular array of natural numbers, where the numbers increment continuously without resetting on new rows.
Because loop variables naturally reset. The column resets to 1 on every new row, but Floyd's Triangle requires a continuous, non-resetting count.
Declare an accumulator or counter variable outside and above the outer loop, and increment it inside the innermost loop.
