Question

A character double occurs when the same character occurs twice in a row, such as the "bb" in "hobbit". Note the character could be a symbol, such as "++" or "!!". For example, the words below all contain character doubles. good hello C++ HOBBIT. Write a full program (starting from #include) that counts the number of character doubles in a phrase entered by the user. The output should look like the example below. Note there are 3 character doubles in this example input: "bb", "oo", and "!!" Enter phrase: Hobbits love cookies!! There are 3 character doubles. You do not have to worry about detecting upper vs. lower-case letters, nor do you have to handle the case when a character occurs three times or more in a row

Explanation / Answer

t=input()
r=t.split()
c=0
for i in range(0,len(r)):
    r1=r[i];
  
    for j in range(0,len(r1)-1):
        if(r1[j]==r1[j+1]):
            c=c+1;
        else:
            continue;
          
print(c)
