Write a function removing that takes MutableMap<Int, String> and value as the input and creates a new MutableMap. The new MutableMap should be the same as the input one, but without the element with the given value. Return the resulting MutableMap. Do not change the original map.
Input: currentMap: MutableMap<Int, String>, value: String
Output: resulting MutableMap<Int, String>
Sample Input:
currentMap: 0 to "Sun", 3 to "Earth", 1 to "Mercury"
value: Sun
Sample Output:
{3=Earth, 1=Mercury}
