#my code down below is not working and I have no idea why. Could someone help?

Triangle <- function(n){

for(i in 0:(n-1)){

s <- ""

for(k in 0:(n-1))

s <- paste(s, " ", sep = "*")

for(j in 0:i){

s <- paste(s, sprintf("%3d", choose(i, j)), sep = "*")}

}

}

print(Triangle(3))

Answer 1

raw_code :

#function to print n*n asterisk
Triangle <- function(n){
for(i in 0:(n-1)){
s <- ""
for(k in 0:i+1){
s <- paste(s," ",sep="*")
}
print(noquote(s)) #printing without quotes
