Alternatively, we can utilize JavaStreamsto achieve the same result with a more concise and functional approach. WithStreams, we can easily group and count the occurrences of characters in the string. Here’s how we can implement it using JavaStreams: @TestpublicvoidgivenString_whenUsingStreams_t...
1. UsingStreamto Count Vowels and Consonants To count the number of vowels and consonants in a String, we can iterate over the characters of the String, and then useCollectors.groupingBy()into two groups. The first group will contain the vowels and the second group will contain the consonants...
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...
** SUBSTITUTE function replaces the character (e) (second argument) with an empty string (third argument).LEN(SUBSTITUTE(A2,"e",""))equals 11 (the length of the string without the character e). If we subtract this number from 12 (total number of characters in cell A2), we get the ...

Input The first line is a single integer T, indicating the number of test cases. 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. ...
