We will use these operators to create a logic, which will return the number of elements in an array. Suppose we have an array called arr. Now, &arr+1 will point to the address of the element after the array. We can dereference it using the * operator and subtract the first element ...

Second largest element in the array : 6 Time complexity: o(n) as array is traversed only once. Space complexity: o(1) as no extra space is used. 5. Handling Edge Cases There are two edge cases which we didn’t handle in the program: Array has less than two elements: If the array...
To find all pairs of elements in Java array whose sum is equal to a given number − Add each element in the array to all the remaining elements (except itself). Verify if the sum is equal to the required number. If true, print their indices. ...
// ArrayList.java /** * 元素数组。 * * 当添加新的元素时,如果该数组不够,会创建新数组,并将原数组的元素拷贝到新数组。之后,将该变量指向新数组。 * * The array buffer into which the elements of the ArrayList are stored. * The capacity of the ArrayList is the length of this array buffer...
Counting the number of elements in each column less than x For this purpose, we will simply access the values of DataFrame by applying a filter of less than 10, and then we will apply thecount()method on the same. Let us understand with the help of an example, ...
