Given a string of lowercase alphabets and a number k, the task is to find the minimum **value** of the string after removal of ‘k’ characters.

The **value** of a string is defined as the sum of squares of the count of each distinct character.

For example consider the string “geeks”, here frequencies of characters are g -> 1, e -> 2, k -> 1, s -> 1 and value of the string is 1^{2 }+ 2^{2 }+ 1^{2 }+ 1^{2} = 7

**Example 1:**

**Input: **S = "abccc", K = 1
**Output:** 6
**Explanation**: Remove one 'c', then frequency
will be a -> 1, b -> 1, c -> 2.
1^{2 }+ 1^{2 }+ 2^{2 }= 6

â€‹**Example 2:**

**Input**: S = "aaab", K = 2
**Output:** 2
**Explanation**: Remove 2 'a's, then frequency
will be a -> 1, b -> 1.
1^{2 }+ 1^{2}^{ }= 2

**Your Task: **

You don't need to read input or print anything. Your task is to complete the function **minValue()** which takes the string **s **as inputs and returns the answer.

**Expected Time Complexity:** O(K*log(|S|))

**Expected Auxiliary Space:** O(constant)

**Constraints:**

1 ≤ K, |S| ≤ 10^{4}
