Which of the following is faster? 1. memset(grid,0,1 010*1010); 2. memset(grid,0,s izeof(grid)); 1. since you initialize only part of the array (typically sizeof(int)/sizeof(char)) but this is probably not what you expected. b) Is there any faster alternative to initializing...
I am using the Dynamic allocation through 'new' keyword for the allocation of chunck of memory for an array, as int *array = new int[size]; //The Size is got by some logic And now on the long run of the logic, I need to parse this array such that i need to get/calculate the...
I have an array A consisting of N integers. I also have an integer K. I want to find out number of different arrays I can obtain from array A by applying the following operation exactly K times. Pick some element in the array and multiply it by -1 array A=[2,3,2] and k=2 I ...
Also the maxnum initialization seem to be in the wrong place. It probably should be placed before the loops, and remember that arrays start at zero and stop at size - 1. You're trying to access the array at size, not size -1. ...
当返回值是一个指针类型,则等于sizeof(void *) 当返回值是int,float,NSInteger,double,long double等常量类型,返回值都是0 当返回值不是上述几种,则返回值为未定义 主要原因是因为,一个方法的调用,会在编译期间翻译成objc_msgSend(receiver, selector, args1, args2, ...)。在运行时才真正知道selector的...
(inta = lowIndex + 1; a < size; a++)//loop that checks every index in the array{if(arrayA[a] % 2 != 0)//if statement to check if the number is an odd number{ sumOfOddNumbers = sumOfOddNumbers + 1;//Adds 1 if the number is an odd number} }returnsumOfOddNumbers; }int...
Edit: In fact, if you go with the principle of least astonishment, if a user calledfindon a json-array, I think they would be least astonished if it behaved likestd::findcalled on a container. as forsize(), I think it should return the same value as if implemented as ...
To be clear: "the code works" means that the codes correctly finds the column of the value in the row of the double array in B.b that is equal to the corresponding row value of the double array in A.a. To be even more clear here is an example. For n = 40, the code...
this is the size of the arrays that I have TestArray.shape Out[159]: (200,24) PredictionArray.shape Out[159]: (200,24) I want to get TP, TN, FP and FN for these arrays I tried this code cm=confusion_matrix(TestArray.argmax(axis=1), PredictionArray.argmax(axis=1...
In the article, we are going to find a subarray which sums to an input sum. This problem came in coding round of Visa, Amazon. Submitted by Radib Kar, on November 22, 2018 Problem Statement: Given an unsorted array A of size N of non-negative integers, find a continuous sub-array...
