Question

我想知道以下哪个功能的计算复杂度较低。背景：我有一个触发信号，该信号触发一个调用我的函数的规则，该规则为某个列表的每个元素添加1。因为该触发信号经常发送，所以我感兴趣的是以下哪些功能。功能1：

;?lon = list of numbers
(deffunction add-one-to-list-of-numbers (?lon)
    (progn$ (?field ?lon)
        (bind ?lon (replace$ ?lon ?field-index ?field-index (+ ?field 1)))
    )
    (return ?lon)
)

功能2：

;?lon = list of numbers
;?cnt = counter
(deffunction add-one-to-list-of-numbers-alt (?lon)
    (loop-for-count (?cnt (length ?lon))
        (bind ?lon (replace$ ?lon ?cnt ?cnt (+(nth$ ?cnt ?lon) 1)))
    )
    (return ?lon) 
)

Answer 1

我建议根据经验进行测试：

<section class="falling-person">
  <div class="bubbles-one"><img src="./assets/images/bubble_01edit.png" alt="" class="img-fluid"></div>
  <div class="container">
    <dov class="row">
      <div class="col-12">
        <div class="image-holder">
          <ul class="falling-scene">
            <li class="layer" id="bubble_splash-layer"><img src="http://www.sharksharkshark.net/testing/assets/images/bubble_splash.png" alt="" class="mx-auto d-block img-fluid splash rellax"></li>
            <li class="layer" id="spotlight-layer"><img src="http://www.sharksharkshark.net/testing/assets/images/spotlight.png" alt="" class="mx-auto d-block img-fluid spotlight rellax"></li>
            <li class="layer" id="man-layer"> <img src="http://www.sharksharkshark.net/testing/assets/images/man.png" alt="" class="img-fluid man rellax"></li>
          </ul>
        </div>
      </div>
    </dov>
  </div>

将一个添加到列表的每个元素的功能更快？
