Survey2Connect Technical Trainee Interview Questions, Process, and Tips

The question asks to find all the pairs present in an array of strings.

• Iterate through the array and compare each element with all other elements to find pairs.

• Store the pairs in a separate array or data structure.

• Consider the order of elements in pairs, i.e., (A, B) is different from (B, A).

The number of steps required to reach the top of a staircase of length n can be calculated using dynamic programming.

• Use dynamic programming to solve the problem

• Create an array to store the number of steps required for each position

• Initialize the first two positions with 1 and 2

• Iterate through the remaining positions and calculate the number of steps based on the previous two positions

• Return the number of steps require

Print the left view of a binary tree

• Traverse the tree in pre-order traversal

• Print the first node encountered at each level

• Maintain a level variable to keep track of current level

• Recursively traverse left subtree first

Print the leftmost node of each level using BFS.

• Implement BFS algorithm to traverse the tree level by level.

• Keep track of the leftmost node of each level.

• Print the leftmost node of each level after traversal is complete.
