Here is the algorithm to print mirrired right triangle star pattern using loop

Take the number of rows(N) of mirrored right triangle as input from user using scanf function.
In any row, the sum of spaces and stars are equal to N. Number of stars increases by one and number of spaces before stars decreases by 1 in consecutive rows.
In any row R, we will first print N-R space characters then R star characters.
