Step by Step solution about How to resolve the algorithm Factorial step by step in the R programming language

Source code in the r programming language

fact <- function(n) {
  if (n <= 1) 1
  else n * Recall(n - 1)
}

factIter <- function(n) {
  f = 1
  if (n > 1) {
    for (i in 2:n) f <- f * i
  }
  f
}

print(factorial(50)) # 3.041409e+64
