Array.prototype.find()是 JavaScript 中的一个数组方法,用于返回数组中满足提供的测试函数的第一个元素的值。否则返回undefined。 基础概念 该方法接收一个回调函数作为参数,这个回调函数会被数组的每个元素依次调用,直到找到一个使回调函数返回true的元素。回调函数本身接收三个参数: ...
This splits the string in the cellAddress variable into an array of substrings using $ as the delimiter. After that, pass the third(2+1) element of the array in the columnNumber variable. Run the code to het the output as shown below. Video Player Media error: Format(s) not supported...
The algo works o(n). Two iterations are required. e.g. array = {1,2,3,-1,-2,4,1,-5,6}; array2={1,3,6,5 , 3, 7,8, 3,9}; so, i = 1, j = 4, the sub array from i+1 to j {3, -1, -2} is the answer....
