## TCS NQT Coding Question-10: Total Fine Collected by Traffic Police

**Problem Statement:** Particulate matters are the biggest contributors to New-Delhi pollution. The main reason behind the increase in the concentration of Particulate matters include vehicle emission by applying Odd Even Number concept for all types of vehicles. The vehicles with the odd number last digit in the registration number will be allowed on roads on odd dates and those with even number last digit will on even dates.

Given an integer array A[], contains the last digit of the registration number of n vehicles traveling on date d(a positive integer). The task is to calculate the total fine collected by the traffic police department from the vehicles violating the rules.

Note: For violating the rule, vehicles would be fined as x Rs.

## TCS NQT Coding Question-9: Single Digit Sum

**Problem Statement:** An intelligence team has received reports about some threats. The reports consist of numbers in a mysterious way. There is a number “n” and another number “r”. Those numbers are studied thoroughly, and it is concluded that all digits of the number ‘n’ are summed up and this action is needed to be performed ‘r’ number of times. The resultant should also be a single digit that is yet to be deciphered. The task here is to find the single digit sum of the given number ‘n’ by repeating the same action ‘r’ number of times.

If the value of ‘r’ is 0, print the output as ‘0’.

## TCS NQT Coding Question-8: Possible Number of Ways

**Problem Statement:** An international conference will be held in India. Presidents from all over the world representing their respective countries will be attending the conference. The task is to find the number of ways possible(P) to make the N members sit around the circular table such that the president of India and prime minister of India will always sit next to each other.
