To print an Hourglass Pattern in R, we use nested loops. The outer loop controls the rows, and the inner loops control the spaces and stars (*) to form the pattern.
In this example,
printHourglass
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from n
to 1 and the inner loops control the spaces and stars in each row.printHourglass <- function(n) {
for (i in n:1) {
cat(' ' * (n - i), '*' * (2 * i - 1), '\n', sep = '')
}
for (i in 2:n) {
cat(' ' * (n - i), '*' * (2 * i - 1), '\n', sep = '')
}
}
# Example usage
printHourglass(5)
