What will be the output of the following C program? If you think it will give a runtime error, you need to mention it. In either case, your answer must include proper justifications without which no credit will be given. #include<stdio.h> main() { unsigned char i, j, a[] = {1, 2, 3, 4, 5} ... j, n); while(j-- != 0) a[0] += n; printf("j = %d, a[0] = %d\n", j, a[0]); }

GATE Overflow | Data Structures | Test 1 | Question: 16
A program takes as input a binary tree (not necessarily balanced) with $n$ nodes and computes for each node, the no. of leaf nodes in the sub-tree rooted at that node. The worst case time complexity of the program is $\Theta(n)$ $\Theta(n \log n)$ $\Theta\left(n^2 \right)$ $\Theta\left(n^2 \log n \right)$
