AnswersYou are given a set of N horizontal lines which are connected by equal number of vertical lines to form squares of size 1x1. Now some segments are removed. You need to count the number of squares of all sizes (1x1, 2x2, ..., NxN) with all sides present.

In the above example you see four horizontal and vertical lines and few missing segments. Now you need to count the number of squares of all sizes with all sides.
Input :
First line is a positive integer N, number of horizontal and vertical lines.
Second line is positive integer M, number of segments removed.
Then there are m lines, each containing V,i,j or H,i,j where i and j are positive integers. H,i,j indicates a horizontal missing segment in the ith horizontal line between the jth and (j+1)th point on the line. V,i,j represents a gap in ith vertical line between the jth and (j+1)th point on the line.
Output :
Is the total number of squares in the figure with all sides along the remaining lines in the figure.
Sample Input :
4
4
H,2,1
H,3,1
V,2,2
V,2,3
Output :
5
Explanation : Here in this figure we have 4 squares of size 1x1 and 1 square of size 3x3, hence total is 5.| Report Duplicate | Flag | PURGE

AnswersThe structure Info stores information of a person. Using a STL map, implement a collection of Info. The fields first and last must be used a unique, composite key. The list should be sorted by last, first in ascending order.typedef struct { string first, last; int age; string addr1, addr2;} Info;Also Using the map of Info from the question, output the list in reverse order. You may not define a new map or redefine the map you defined in the last question.

AnswersThe stepping number:
- Anon October 13, 2014 in United States
A number is called as a stepping number if the adjacent digits are having a difference of 1. For eg. 8,343,545 are stepping numbers. While 890, 098 are not. The difference between a ‘9’ and ‘0’ should not be considered as 1.
Given start number(s) and an end number(e) your function should list out all the stepping numbers in the range including both the numbers s & e.| Report Duplicate | Flag | PURGE
