1. When does the + operator concatenate instead of add? What happens if you try to use + on a string with an integer? Why do you think this happens? 2. If a string has 10 characters, what is the index of the last character? 3. Explain why this code causes an exception: Animal = "Tiger" Animal[0] = "L"

Hi in the below code I would like to remove the blank tokens and how to achieve it.   #include <stdio.h> #include <string.h> #include <stdlib.h> int count_tokens(const char* str) {     int count = 0;     int invalidToken = 0; // set false     for(int i = 0; i <= strlen(str); i++) {         if( i == strlen(str) || str[i] == 32){ // if past end of string, or if space             if(invalidToken) {                 invalidToken = 0; // set false                 continue;             }             else {                 count++; // increment count only if token was not invalid                 continue;             }         }         if( !(str[i] >= 97 && str[i] <= 122) ) { // if not lowercase letter             invalidToken = 1; // set true         }     }     return count; } char** split_tokens(const char* str) {     char **tokenArr;     tokenArr = (char **) malloc(count_tokens(str) * sizeof(char*)); /*use count_tokes() to determine the length*/     int…

Implement the following function: Code should be written in python.

What's Hiding Amongst the Crowd? Language - Java Script A word is on the loose and now has tried to hide amongst a crowd of tall letters! Help write a function to detect what the word is, knowing the following rules: The wanted word is in lowercase. The crowd of letters is all in uppercase. Note that the word will be spread out amongst the random letters, but their letters remain in the same order. ● Examples detectWord("UcUNFYGaFYFYGtNUH") → "cat" detectWord("bEEFGBuFBRrHgUHINFYaYr") → "burglar" detectWord("YFem HUFBbezFBYZF BYLleGBYEFGBMENTment") → "embezzlement"

C++ . Please make sure code has "Enter integer 1, etc" instead of allowing you to type integers without prompt.

String spell = "Redikulus"; How would you find the index of the 'u' just before the last 's' using a single line of code?  Multiple answers may be correct.  Given the string String spell = "Redikulus"; How would you find the index of the 'u' just before the last 's' using a single line of code?  Multiple answers may be correct.   A. spell.substring(5, spell.length()).indexOf('u'); B. spell.indexOf('u', 5); C. spell.lastIndexOf('u'); D. spell.contains('u'); E. spell.indexOf('u', spell.length() - 2); F. spell.indexOf('u', spell.indexOf('l'));

Please don’t use chegg C++ programming You are playing a mobile game with circular balls. At the beginning, you are given an string representing an array of integers where every element represents radius of the circle. At every stage, you need to pick the two largest circles and merge them together according to following set of rules: ​1)If r1 == r2, both circles are vanished ​2) If r1 != r2, find abs(r1 - r2) as new radius and replace it higher radius circle and ​ then remove the other circle. At the end of the game, there will be at most one circle left. If there are no circle left, return 0. Otherwise return the radius of the last circle. You MUST use a Priority Queue implementation to receive credit. You may NOT use STL to implement the Priority Queue directly, however you are allowed to use vectors and such. ​ Case 1:​​Input 1: 3 3​​​​ Output 1: 0 ​Case 2:​​Input 2: 1 2 3 1​​​ Output 2: 1 ​Case 3:​​Input 3: 30 80 50 10 90 20 50​​Output 3: 10
