In this program, we will take a string as input and find the least frequent character in a string.
Steps to solve the program
- Take a string as input and create an empty dictionary.
- Use For loop to iterate over each character of the string.
- Add the character as the key and its occurrences in the string as its value in the dictionary.
- Find first the character having the least frequency from the value of the keys using min().
- Print the output.
#Input string
string = "abcdabdggfhf"
char_freq = {}
for char in string:
if char in char_freq:
char_freq[char] = char_freq[char]+1
else:
char_freq[char] = 1
result = min(char_freq, key = char_freq.get)
#Printing output
print("Least frequent character: ",result)
Output :
Least frequent character: c
