Can you solve this real interview question? Sort Characters By Frequency - Given a string s, sort it in decreasing order based on the frequency of the characters. The frequency of a character is the number of times it appears in the string. Return the s
Example 1 illustrates how to sort a table object by frequency counts in increasing order.For this task, we can apply the order function as shown below:my_tab_sort1 <- my_tab[order(my_tab)] # Order table my_tab_sort1 # Print ordered table # x # a e b c d # 1 1 2 2 3...
