Suppose we have an array called nums of positive integers. We have to select some subset of nums, then multiply each element by an integer and add all these numbers. The array will be a good array if we can get a sum of 1 from the array by any ... Read More

In this article we will find all those elements from a list which start with specific letter.With index and lowerWe use the lower function so that the test later can match with the first letter of the the elements in the list irrespective of the case. Then we use the ... Read More

Suppose we have a rectangle of size n x m. We have to find the minimum number of integers sided square objects that can tile the rectangles.So, if the input is like n = 2 and m = 3, then the output will be 3, as we need three blocks.To ... Read More
