javascript - How to delete last white space in the array when concatenating? -

-

i need have javascript alert without space between last word , exclamation mark.

the final alert should like:

i own garden verymuchmuch verymuchmuch!

here code have space before.

  var inittext, closetext, msg = "";   var i, j, k;   var myarray = new array(3);  myarray[0] = "my";  myarray[1] = "own";  myarray[2] = "garden";    inittext = "i ";    closetext = "!";    (k=0; k < 3; k++) {     inittext = inittext + myarray[k] + " ";   }   (j=0; j < 2; j++){     inittext = inittext + "very";     (i=0; < 2; i++){            inittext = inittext + "much";       }     inittext = inittext +" ";   }     msg = inittext + closetext;    alert(msg);

you check not add white space in way:

var inittext, closetext, msg = "";   var i, j, k;   var myarray = new array(3);  myarray[0] = "my";  myarray[1] = "own";  myarray[2] = "garden";    inittext = "i ";    closetext = "!";    (k=0; k < 3; k++) {     inittext = inittext + myarray[k] + " ";   }   (j=0; j < 2; j++){     inittext = inittext + "very";     (i=0; < 2; i++){            inittext = inittext + "much";       }     inittext = inittext + (j<1 ? " " : "");   }     msg = inittext + closetext;    alert(msg);

or can trim inittex variable msg = inittext.trim() + closetext;

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
