### Maximum Strictly Increasing Cells in a Matrix

The problem revolves around navigating an integer matrix from a starting cell following a set of rules. The task is to determine the maximum number of cells that can be visited. ### Number of Pairs Satisfying Inequality

The problem involves two arrays, and an integer diff. The task is to count the number of pairs (i, j) satisfying an inequality. ### Find K Pairs with Smallest Sums

The goal is to find the k pairs formed by choosing one element from each array. These pairs have the smallest sums among all possible combinations of elements from both arrays. ### K Radius Subarray Averages

The task is to compute running average of an array. We must do it efficiently. ### Make Array Strictly Increasing

The task involves finding the minimum number of operations, where each operation consists of replacing an element in an array with an element from another, to make source array strictly increasing.
