They are something like brain tests. Something like practice problems for the GATE and other Campus interview tests. I tried to solve it, but couldnt even find a proper solution to write the code. Im… Re: Tough Problem [C and C++] 14 Years Ago by csurfer Its quite straight forward right ? Assuming int n = strlen( <Message> ); Then the order of the matrix say ord should be the smallest integer i which satisfies the equation i*i*2 >= n ( where i is the smallest integer which satisfies this equation ) Now for any square matrix of odd order you can device an algorithm by which you can … Re: Tough Problem [C and C++] 14 Years Ago by stevanity Thats wat. I have found out a way to compute the matrix order and store string int it. Ive tried so hard to find out an algorithm to traverse the matrix. But its so confusing. Please can anyone provide the algorithm only . EDIT: After Much Research and editing of other codes, ive found a code to traverse spirally in the matrix of order N*N. [… Re: Tough Problem [C and C++] 14 Years Ago by csurfer @Stevanity : Nothing comes on a platter. do you really think you had to look at others codes for the above code snippet you have posted ? You could spend some time how you want to move in the array and yourself write the code. Now after having the above code you want to know how to traverse the opposite way the above code is traversing(i,e from … Re: Tough Problem [C and C++] 14 Years Ago by stevanity hey im trying man Ive been doing the same man. Still I cant figure out. Coz i think there is no logical relation between the two paths. Ive been trying to solve the problem for a week now. only after that Ive asked for help Re: Tough Problem [C and C++] 14 Years Ago by Fbody Start by finding the center of the matrix, then expand your algorithm from there. If you have an N x N matrix, where is the center? Re: Tough Problem [C and C++] 14 Years Ago by stevanity My matrix's order would be odd SO the centre would precisely be the cell with index [N/2][N/2] But how do i spiral out. It seems impossible to modify the above code. Re: Tough Problem [C and C++] 14 Years Ago by csurfer In a 3X3 matrix from the centre the flow is 1L,1U,2R,2D,2L for 5X5 it is 1L,1U,2R,2D,3L,3U,4R,4D,4L But in general it is always of the form: 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,........ L,U,R,D,L,U,R,D,............................ where numbers represent the times you need to move and L=left,U=Up,R=Right,D=Down moving left is decrementing j … Re: Tough Problem [C and C++] 14 Years Ago by stevanity Thanks man Exactly wat im looking for i think i can pick up from this. But when to stop? Re: Tough Problem [C and C++] 14 Years Ago by nbaztec After n*n iterations, duh. (n is order). This is when you've read all the elements in the matrix. Re: Tough Problem [C and C++] 14 Years Ago by Fbody You'll most likely have to keep track of your previous row and column values to generate the spiral. Then, if you follow the sequence csurfer cave you, you will always start at matrix[N/2][N/2] and end at matrix[N][0]. Re: Tough Problem [C and C++] 14 Years Ago by stevanity Thanks for all the Help Guyz The tip about the number of UP and DOWN and RIGHT and LEFT movements in each step opened my eye.

Due to this someone may just copy it out and never learn the way you learnt. To a student learning is more important than getting the job done :) Re: Tough Problem [C and C++] 14 Years Ago by stevanity can anyone cut the code out for me Im not able to edit it Re: Tough C++ Problems 12 Years Ago by ddanbe A program to print out the squares of the numbers 1 to 9 can be really though if you're just starting to learn to program.(In any language) Re: Tough C++ Problems 12 Years Ago by $Tweety$ I mean i hav done spirals, d coin game n other such programs. I have also written sum of the games like ic-tac-toe,hangman etc..
