TCS digital questions and solutions of TCS digital exam conducted today (20th July 2018) are discussed here. TCS digital questions and solutions would give you a rough idea of your performance and score in the exam.
In most colleges, the test was conducted in 3 slots. People who attempted TCS digital mock test found it helpful since the pattern is very similar to the mock. However, people found the actual exam to be way tougher than the mock test.
There are no questions getting repeated between the slots. No negative marking for Fill-ups and there is a negative marking for MCQs
TCS is likely to announce the TCS digital exam results tomorrow. While others are waiting for results, you can analyze our TCS digital questions and solutions to know your approximate score.

Question 18: Levenshtein distance is a string metric for measuring the difference between two sequences informally, the Levenshtein distance between two words is the minimum number of single-character edits(insertions, deletions or substitutions)required to change one word into the other. These edits (insertions, deletions or substitutions) may carry the same weightage or different weightage. Let us say we want to find the Levenshtein distance between “Kittens” and “sitting†if the weightage of substitution, insertion, insertion and deletion are 1 respectively. what is the Levenshtein distance between these words based on the said weightages?
Question 19: How many points required from “kittens†to “sittingâ€, Points substitute – 3, Insertion-2, deletion – 1.
Answer: 9
