A programming language is a formal constructed language designed to communicate instructions to a machine, particularly a computer. Thousands of different programming languages have been created, mainly in the computer field, and many more still are being created every year. The description of a programming language is usually split into the two components of syntax (form) and semantics (meaning). Some languages are defined by a specification document (for example, the C programming language is specified by an ISO Standard), while other languages (such as Perl) have a dominant implementation that is treated as a reference. Some languages have both, with the basic language defined by a standard and extensions taken from the dominant implementation being common.

Hi,

public Map<String, String> topping2(Map<String, String> map) {
  if(map.get("ice cream")!=null){
    map.put("yogurt", map.get("ice cream"));
  }
  if(map.get("spinach")!=null){
    map.put("nuts", map.get("spinach"));
  }
  else{
    map=map;
  }
  return map;
}

how above code different from below code

public Map<String, String> topping2(Map<String, String> map) {
//public Map < String, String > topping1(Map < String, String > map) {
   // map.put("spinach", "nuts");
    if (map.containsKey("spinach")) {

Hi,

How below solution is different from

public Map<String, String> topping3(Map<String, String> map) {
 // Map<String, String> map=null;
  if(map.get("potato")!=null){
    map.put("fries",map.get("potato"));
  }
    if(map.get("salad")!=null){
    map.put("spinatch",map.get("salad"));
  }
  else
  map=map;
  return map;
  
}

Open in new window


below solution

public Map < String, String > topping3(Map < String, String > map) {
   // map.put("bread", "butter");
    if (map.containsKey("potato")) {
        map.put("fries", map.get("potato"));

    }
     if (map.containsKey("salad")) {
        map.put("spinach", map.get("salad"));

    }
    return map;
}

I created a x64 context menu shell extension in C++, which works fine when I right click a file or folder in the file list. But when I right click on a directory in the directory tree on the left Windows Explorer crashes, with no error details.

Any idea what can cause this to happen only in the directory tree?

Hi,

I am trying to double list numbers using functionala lamda programming


http://codingbat.com/prob/p117665
Given a list of integers, return a list where each integer is multiplied by 2.

doubling([1, 2, 3]) → [2, 4, 6]
doubling([6, 8, 6, 8, -1]) → [12, 16, 12, 16, -2]
doubling([]) → []

Open in new window


Solution:

public List<Integer> doubling(List<Integer> nums) {
  nums.replaceAll(n -> n * 2);
  return nums;
  
  // OR the equivalent java streams solution:
  // return nums.stream()
  //  .map(n -> n * 2)
  //  .collect(Collectors.toList());
}

hi,

http://codingbat.com/prob/p136950

for above challenge
Map-1 > mapAB4
prev  |  next  |  chance

Modify and return the given map as follows: if the keys "a" and "b" have values that have different lengths, then set "c" to have the longer value. If the values exist and have the same length, change them both to the empty string in the map.

mapAB4({"a": "aaa", "b": "bb", "c": "cake"}) → {"a": "aaa", "b": "bb", "c": "aaa"}
mapAB4({"a": "aa", "b": "bbb", "c": "cake"}) → {"a": "aa", "b": "bbb", "c": "bbb"}
mapAB4({"a": "aa", "b": "bbb"}) → {"a": "aa", "b": "bbb", "c": "bbb"}

what are input parameters for the method.

what is the return for it?


"a": "aaa", "b": "bb", "c": "cake"//is these are bunch of string values pretending to be key and value for a map??

please advise on how to understand and approach this challenge
