Here, we will create a user define function that acceptsan arrayin an integerpointer, and then we will access array elements using the pointer and calculate the sum of all array elements and return the result to the calling function. Calculating the sum of array elements using pointers...

A better solution is using two pointers instead of one. This makes time complexity of O(n^2). To avoid duplicate, we can take advantage of sorted arrays, i.e., move pointers by >1 to use same element only once. 1:publicArrayList<ArrayList<Integer>> threeSum(int[] num) { 2: ArrayL...

We have sorted the array using sort() method, declared a count variable and currSum that stores the sum of pairs of element. Then we have defined two pointers, left and right where left pointer represents first element of the array and right pointer points to last element of the array. ...
Given an arrayAAof lengthNNwith positive elementsa1,a2,...,aNa1,a2,...,aNand two numbersLLandRR. Divide the array into minimum number of sub-arrays such that each subarray have sum in the range[L,R][L,R]. I thought of two pointers approach but I am sure how to take care of the...
