Given a string, find the number of different characters in it.

Example

For s = "cabca", the output should be
differentSymbolsNaive(s) = 3.

There are 3 different characters a, b and c.

Input/Output

Find the leftmost digit that occurs in a given string.

Example

For inputString = "var_1__Int", the output should be
firstDigit(inputString) = '1';
For inputString = "q2q-q", the output should be
firstDigit(inputString) = '2';
For inputString = "0ss", the output should be
firstDigit(inputString) = '0'.

Given array of integers, remove each kth element from it.

Example

For inputArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] and k = 3, the output should be
extractEachKth(inputArray, k) = [1, 2, 4, 5, 7, 8, 10].

Input/Output

[time limit] 4000ms (py3)

Given an array of equal-length strings, check if it is possible to rearrange the strings in such a way that after the rearrangement the strings at consecutive positions would differ by exactly one character.

Example

For inputArray = ["aba", "bbb", "bab"], the output should be
stringsRearrangement(inputArray) = false;

All rearrangements don't satisfy the description condition.
For inputArray = ["ab", "bb", "aa"], the output should be

	while (true) {

	if (index >= 0) {
	++count;
	++index;
	} else break;
	}
	return count;
