Q4 (10 pts). What is the output of the code shown below. Explain your answer. You must clearly demonstrate you understood the algorithm. Hint: Remember a char is also a number between 0-254. For example 'a' is 97, the space character ' ' is #include <stdio.h> #include <stdbool.h> void dummyFunc(char str); int main() { char str[] = "Hi there friend"; dummyFunc(str); printf("%s", str); } void dummyFunc(char* str) { int i, j; bool dummy[255] = {0}; for (i = 0, j = 0; *(str + i) != '\0'; i++) { if (dummy[str[i]]) { dummy[str[i]] = false; } else { dummy[str[i]] = true; } } *(str + j) = *(str + i); }
