Count new pairs of strings that can be obtained by swapping first characters of pairs of strings from given array | Function to count newly created pairs by swapping the first characters of any pairs of strings.
Stores the count all possible pair of strings.
Push all the strings into the Unordered Map.
Generate all possible pairs of strings from the array arr [ ].
Store the current pair of strings.
Swap the first character.
Check if both string are not present in map.
