saleemkce / shortest sub-segment finding.php

Last active January 2, 2016 09:29

Given a paragraph of text, write a program to find the first shortest sub-segment that contains each of the given k words at least once. A segment is said to be shorter than other if it contains less number of words.

	<?php
	/*
	Given a paragraph of text, write a program to find the first shortest sub-segment that contains each of the given k words at least once. A segment is said to be shorter than other if it contains less number of words.
	Ignore characters other than [a-z][A-Z] in the text. Comparison between the strings should be case-insensitive.
	If no sub-segment is found then the program should output “NO SUBSEGMENT FOUND”.

	Input format :

	First line of the input contains the text.
	Next line contains k , the number of words given to be searched.

	Event time will be of form HH MM ( where 0 <= HH <= 23 and 0 <= MM <= 59 ), K will be in the form minutes.

	Input Format:

	M K [ M number of busy time slots , K is the duration in minutes ]
	Followed by M lines with 4 numbers on each line.
	Each line will be of form StartHH StartMM EndHH EndMM [ Example 9Am-11Am time slot will be given as 9 00 11 00 ]

saleemkce / connected-cli

Created January 6, 2014 14:34

Given a 2–d matrix , which has only 1’s and 0’s in it. Find the total number of connected sets in that matrix.

	<?php
	/*
	Given a 2–d matrix , which has only 1’s and 0’s in it. Find the total number of connected sets in that matrix.


	Explanation:
	Connected set can be defined as group of cell(s) which has 1 mentioned on it and have at least one other cell in that set with which they share the neighbor relationship. A cell with 1 in it and no surrounding neighbor having 1 in it can be considered as a set with one cell in it. Neighbors can be defined as all the cells adjacent to the given cell in 8 possible directions ( i.e N , W , E , S , NE , NW , SE , SW direction ). A cell is not a neighbor of itself.


	Input format :

saleemkce / fibonacci

Last active January 2, 2016 09:29

Given a number K, find the smallest Fibonacci number that shares a common factor( other than 1 ) with it. A number is said to be a common factor of two numbers if it exactly divides both of them. Output two separate numbers, F and D, where F is the smallest fibonacci number and D is the smallest number other than 1 which divides K and F.

	Output two separate numbers, F and D, where F is the smallest fibonacci number and D is the smallest number other than 1 which divides K and F.

	Input Format

	First line of the input contains an integer T, the number of testcases.
	Then follows T lines, each containing an integer K.
