To find duplicate characters in a string, you can use a set to track characters you've encountered as you iterate through the string. For each character, check if it already exists in the set; if it does, it's a duplicate. If it doesn't, add it to the set. Alternatively, you can use a dictionary to count occurrences of each character and identify those that appear more than once.

What is steps to calculate fallow of string?
To calculate the fallow of a string, follow these steps: First, identify the string for which you want to calculate the fallow. Next, determine the frequency of each character in the string. Then, find the average frequency of characters and measure how much each character's frequency deviates from this average. Finally, sum these deviations to obtain the overall fallow value.
