EasyR15 min10 XP

Problem

Given df with name and score, return rows sorted by score descending.

Sorting is necessary for top-N reports and sanity checks in analysis.

Example 1

InputA=5, B=9, C=7

OutputB, C, A

Negative score makes order sort descending.

CodeR

df <- data.frame(
  name = c("A", "B", "C"),
  score = c(5, 9, 7)
)

# write your code here

df <- data.frame(
  name = c("A", "B", "C"),
  score = c(5, 9, 7)
)

# write your code here
