For each case, the first line is an integer n (1 <= n <= 200000), which is the length of string s. A line follows giving the string s. The characters in the strings are all lower-case letters. Output For each case, output only one number: the sum of the match times for all...
With Streams, we can easily group and count the occurrences of characters in the string. Here’s how we can implement it using Java Streams: @Test public void givenString_whenUsingStreams_thenVerifyCounts() { Map<Character, Integer> charCount = str.chars() .boxed() .collect(toMap( k ->...
