This post will discuss how to find the index of the first occurrence of an element in a C++ array.1. Using std::findThe C++ standard library offers the std::find function which returns an iterator to the first matching element in the specified range, or an iterator to the end of the ...
This program finds the largest interger in the array. I am trying to understand it but I am struggling with the recursion. For example in line 19: max = recursiveMaximum(arr, first+1, last); How can we put the argument with 3 elements in an integer? Could someone explain the ...
Suppose a sorted array is rotated at some pivot unknown to you beforehand. (i.e.,0 1 2 4 5 6 7might become4 5 6 7 0 1 2). Find the minimum element. You may assume no duplicate exists in the array. 解题思路: 最朴素的O(n)的方法,就是找到突然变小的那个元素,肯定是最小的。否则...
