	arjun: 2015-11-06 05:35:12 Declare all the variables as Global and the char array size must be >=2001. Costed me 1 WA. Watch this: https://www.youtube.com/watch?v=We3YDTzNXEk

	dwij28: 2015-08-31 19:35:47 Brilliant question, worth the 3 hours spent, learnt so much, a must for beginners like me.. You could refer to this link for help : ( https://www.youtube.com/watch?v=We3YDTzNXEk ) Just a small issue, I used gets() in C and got a WA, just changed it to scanf() and got an AC. Is the input poorly fomatted ? Weird :/

	ultimatedbz: 2015-08-28 03:55:10 "those who are getting SIGSEGV fault declare 2-D dynamic array globally with size 3000.." -anuveshkothari is right
	monkz: 2015-08-26 20:27:03 Can it be solved using LCS?
	anuveshkothari: 2015-08-18 16:45:17 declaring char array globally instead of dynamic array costed in 3 segmentation error... those who are getting SIGSEGV fault declare 2-D dynamic array globally with size 3000.. Last edit: 2015-08-18 16:45:45
	rahulwahi: 2015-08-08 20:05:58 declare 2D array Globally if u are getting SIGSEGV fault
