Test instructionsGiven a n*m lattice, each lattice is dyed black or white. Now to cover these squares with 1 * 2 bricks, it is required that the blocks and blocks do not overlap each other, and that all white squares are covered, but no black squares are covered. Find out how many kinds of coverage methods, the output scheme number to m after the result of the remainder.Input:N= 3M= 4The color of each lattice is as follows (. = white, x for Black).... x....Output:2Analysis:Since the black lattic

Title: give you a 3*n ground, with 1*2 floor tile paved, ask there are several methods.Analysis: Combinatorial mathematics, dynamic programming. First find the ground to push the relationship.Only an even number is meaningful, and an odd total area of an odd number must not be true. Once we looked at the two columns as a unit.If, the last 2 columns constitute a whole part (3 cases, 2*3 3), then there is 3*f (n-2) method;If, the last 4 columns constitute a whole part (2 cases, upside down impleme

We analyze, the solution of the problem: since it is the difference in width understanding, only need to tell the browser page container width, the width of the head element can not be less than the width of the content layer. When the browser window shrinks, the minimum width of the page container and the head element remains the width of the content layer. This solves the problem on the width.The CSS code is:#wrap {width:100%;Background: #ddd;Width:expression (document.body.clientW
