Binary search is a fast search algorithm with run-time complexity of (log n). This search algorithm works on the principle of divide and conquer, since it divides the array into half before searching. For this algorithm to work properly, the data collection should be in the sorted form. Bi...
Inside the loop, calculate the index of the middle element of the current search space using the formula: mid = (left + right) // 2 Check whether the middle element of the current search space is equal to the target element. If it is, return the index of the middle element. ...

此处可以用暴力求解法以及二分查找法(会节省更多时间)。而二分查找是有对应的STL的。此处是可以用binary_search,是在有序数列中确定给定的元素是否存在。 #include <iostream>#include<algorithm>usingnamespacestd;inta[501],b[501],c[501],sum[250010],s[1001];intmain() ...
Ouadfel and Abd (2020) propose a new approach based on the crow search algorithm (CSA) for feature selection with the global search strategy and the adaptive awareness probability. Hu et al. (2020) analyze the range of parameters and introduce a new updating formula for these parameters to ...
In the average case, it takes only a few microseconds for the binary search to find one element among all nine million! Other than that, the number of comparisons for the chosen elements remains almost constant, which coincides with the following formula: Finding most elements will require the...
