How do you find the middle element of a string in Python?

If the string length is even string[len(string)//2 – 1] is the first of the middle characters and string[len(string)//2] is the second. Just calculate the index.

How do you find the middle of a string?

Here are the following steps to get the middle character of string.

1. Calculate the length of string ie len= str. getLength();
2. Calculate the middle index len/2.
3. Get character at mid index str.charAt(mid-1);//for odd length for even you need to both str.charAt(mid-1), str.chartAt(mid);

Which method return the length of the string?

The length() method returns the length of a specified string.

How do you get distinct characters and counts in a string?

Given a string, find the all distinct (or non-repeating characters) in it….Traverse the input string str and do following for every character c = str[i].

1. Increment count[x].
2. If count[x] is 1, then store index of x in index[x], i.e., index[x] = i.
3. If count[x] is 2, then remove x from index[], i.e., index[x] = n.

How do you extract a character from a string in Python?

Using ord(char)

1. Get the input from the user using the input() method.
2. Declare an empty string to store the alphabets.
3. Loop through the string: If the ASCII value of char is between 65 and 90 or 97 and 122. Use the ord() method for the ASCII values of chars. Add it to the empty string.
4. Print the resultant string.

Which function is used to extract character from the middle of string?

Excel MID function
The Excel MID function extracts a given number of characters from the middle of a supplied text string. For example, =MID(“apple”,2,3) returns “ppl”. The characters extracted.

How do you put a character in the middle of a string in Java?

Approach:

1. Get the Strings and the index.
2. Create a new String.
3. Insert the substring from 0 to the specified (index + 1) using substring(0, index+1) method. Then insert the string to be inserted into the string.
4. Return/Print the new String.

Which method can be used to return a string in upper case letters?

The toUpperCase() method converts a string to upper case letters. Note: The toLowerCase() method converts a string to lower case letters.

What is returned by length?

The string length method returns the number of characters written in the String. This method returns the length of any string which is equal to the number of 16-bit Unicode characters in the string.

What is distinct character?

Here distinct characters is used in literal sense. It means different characters. For example : ‘a’ and ‘b’ are distinct while ‘a’ and ‘a’ are same. So, a string say, “absgj” contains 5 distinct characters.

How do you find unique characters in a string in C++?

First we will initialize all values of counter array to 0 and all values of index array to n (length of string). On traversal of the string str and for every character c, increase count[x], if count[x] = 1, index[x] = i. If count[x] = 2, index[x] = n. Sort indexes and print characters.

What happens if the length of the string is odd?

If the length of the string is odd return the middle character and return the middle two characters if the string length is even. Are you sure? Resetting will undo all of your current changes. Share Your Code! pro tip You can save a copy for yourself with the Copy or Remix button.

How many middle characters are there in an odd string?

Therefore, there would be two middle characters ‘a’ and ‘v’, we print the second middle character. The length of the given string is odd. Therefore, there would be only one middle character, we print that middle character.

Why can’t I find the substring in odd_string?

Obviously you can’t str.find the substring ‘2’ in odd_string, because it was never there. str.find returns -1 if it cannot find the substring; you should use str.index instead, which gives you a nice clear ValueError when it can’t find the substring.
