OLX Interview Questions, Process, and Tips

The question is asking for a variation of sorting an array containing 0s, 1s, and 2s.

• Use a three-way partitioning algorithm to sort the array in a single pass.

• Keep track of three pointers - low, mid, and high to partition the array.

• Example: Input array = [0, 1, 2, 1, 0], Output array = [0, 0, 1, 1, 2]

A palindromic substring is a string that reads the same forwards and backwards.

• Use dynamic programming to find the longest palindromic substring.

• Start by considering each character as the center of a potential palindrome.

• Expand outwards from each center to check for palindromic substrings.

• Keep track of the longest palindrome found so far.

• Example: Input 'babad', Output 'bab' or 'aba'.

Rank assigns unique ranks to each distinct value, while Dense Rank assigns consecutive ranks to each distinct value.

• Rank does not skip ranks when there are ties, while Dense Rank does

• Rank will have gaps in ranks if there are ties, while Dense Rank will not

• Rank function is used to assign a unique rank to each distinct row, while Dense Rank function is used to assign consecutive ranks to each distinct row
