| Write a Java program to find the second smallest element in an array. | |
| Write a Java program to add two matrices of the same size | |
| For example, if we have two metrices | |
| 1 2 3 . 1 2 3 . 2 4 6 | |
| 2 3 5 + 1 2 3 = 3 5 8 | |
| 3 2 4 2 0 1 . 5 2 5 | |
| 1. Reverse a string using stack | |
| 2. Given an expression string exp , write a program to examine whether the pairs and the orders of “{“,”}”,”(“,”)”,”[“,”]” are correct in exp. | |
| Example: | |
| Input: exp = “[()]{}{[()()]()}” | |
| Output: Balanced | |
| Input: exp = “[(])” | |
| Output: Not Balanced | |
| 3. We are given a string having parenthesis like below | |
| “( ((X)) (((Y))) )” | |
| We need to find the maximum depth of balanced parenthesis, like 4 in above example. Since ‘Y’ is surrounded by 4 balanced parenthesis. | |
| If parenthesis are unbalanced then return -1. |
