Blade logic interview question. 1st round is a written tests with 15 multiple questions from c and c++. All are simple basic question. Like int main () { Int i=65; Return printf(ā€œ%cā€, i); } 2nd and 3rd round is technical interview. The position for which I was interview was core UNIX and c. Yes it is for system programming. The company has product name blade server. For their server they are creating their own command for their purpose. Example cd command. We can implement it in a c program by using the chdir() function. So the question asks related to PID, fork, pipe, shared memory, signal. Write a program in c which will act as cp command.

You have given 2 array. You need to find whether they will create the same BST or not. For example: Array1:10 5 20 15 30 Array2:10 20 15 30 5 Result: True Array1:10 5 20 15 30 Array2:10 15 20 30 5 Result: False One Approach is Pretty Clear by creating BST O(nlogn) then checking two tree for identical O(N) overall O(nlogn) ..we need there exist O(N) Time & O(1) Space also without extra space .Algorithm ?? DevoCoder guest Posted 3 months ago # #define true 1 #define false 0 int check(int a1[],int a2[],int n1,int n2) { int i; //n1 size of array a1[] and n2 size of a2[] if(n1!=n2) return false; //n1 and n2 must be same for(i=0;ia1[i+1]) && (a2[i]>a2[i+1]) ) ) return false; } return true;//assumed that each array doesn't contain duplicate elements in themshelves }
