using c language String Challenge Have the function StringChallenge(str) read str which will contain two strings separated by a space. The first string will consist of the following sets of characters: +, *, $, and {N} which is optional. The plus (+) character represents a single alphabetic character, the ($) character represents a number between 1-9, and the asterisk (*) represents a sequence of the same character of length 3 unless it is followed by {N} which represents how many...
Given a String str, and a char c return the number of times that c appears inside str. countChar("Abcdefg", 'a') returns 1 countChar("xxXx", 'x') returns 4 countChar("", 'q'') returns 0 ----------------- Please use java public class Count { public int countProblem(String str, char c) { int res = 0; //Your work is here return result; } }
public static int countCharacter(String str, char c) { // This recursive method takes a String and a char as parameters and // returns the number of times the char appears in the String. You may // use the function charAt(int i) described below to test if a single // character of the input String matches the input char. // For example, countCharacter(“bobbie”, ‘b’) would return back 3, while // countCharacter(“xyzzy”, ‘y’) would return back 2. // Must be a RECURSIVE...
