Suppose we have an integer array nums, we have to find the number of range sums that lie in range [lower, upper] both inclusive. The range sum S(i, j) is defined as the sum of the elements in nums from index i to index j where i ≤ j.So if the input is like [-3, 6, -1], lower = -2 and upper = 2, then the result will be 2, as the ranges are [0, 2], the sum is 2, [2, 2], sum is -2.To solve this, we will follow these steps −Define a function mergeIt(), this will take array ...

Suppose we have two arrays of length m and n with digits 0-9 representing two numbers. We have to create the maximum number of length k that is less than m + n from digits of the two. We have to keep in mind that the relative order of the digits from the same array must be preserved. We have to find the array of the k digits. So if the inputs are like [3, 4, 7, 5] and [9, 1, 3, 5, 8, 4], and k = 5, then the answer will be [9, 8, 7, 5, 4].To solve ... Read More
