Below are the most asked accenture coding questions till 2024
Question 1: Rat Count House
(Asked in Accenture OnCampus 10 Aug 2022, Slot 1)
Problem Description :
The function accepts two positive integers ‘r’ and ‘unit’ and a positive integer array ‘arr’ of size ‘n’ as its argument ‘r’ represents the number of rats present in an area, ‘unit’ is the amount of food each rat consumes and each ith element of array ‘arr’ represents the amount of food present in ‘i+1’ house number, where 0 <= i
Note:
- Return -1 if the array is null
- Return 0 if the total amount of food from all houses is not sufficient for all the rats.
- Computed values lie within the integer range.
Example:
Input:
- r: 7
- unit: 2
- n: 8
- arr: 2 8 3 5 7 4 1 2
Output:
4
Explanation:
Total amount of food required for all rats = r * unit
= 7 * 2 = 14.
The amount of food in 1st houses = 2+8+3+5 = 18. Since, amount of food in 1st 4 houses is sufficient for all the rats. Thus, output is 4
Question 2:
(Asked in Accenture OnCampus 11 Aug 2022, Slot 1)
You are given a function,
int findCount(int arr[], int length, int num, int diff);
The function accepts an integer array ‘arr’, its length and two integer variables ‘num’ and ‘diff’. Implement this function to find and return the number of elements of ‘arr’ having an absolute difference of less than or equal to ‘diff’ with ‘num’.
Note: In case there is no element in ‘arr’ whose absolute difference with ‘num’ is less than or equal to ‘diff’, return -1.
Example:
Input:
- arr: 12 3 14 56 77 13
- num: 13
- diff: 2
Output:
3
Explanation:
Elements of ‘arr’ having absolute difference of less than or equal to ‘diff’ i.e. 2 with ‘num’ i.e. 13 are 12, 13 and 14.
Question:3
(Asked in Accenture OnCampus 12 Aug 2022, Slot 1)
Implement the following Function
def ProductSmallestPair(sum, arr)
The function accepts an integers sum and an integer array arr of size n. Implement the function to find the pair, (arr[j], arr[k]) where j!=k, Such that arr[j] and arr[k] are the least two elements of array (arr[j] + arr[k] <= sum) and return the product of element of this pair
NOTE
- Return -1 if array is empty or if n<2
- Return 0, if no such pairs found
- All computed values lie within integer range
Example
Input
sum:9
size of Arr = 7
Arr:5 2 4 3 9 7 1
Output
2
Explanation
Pair of least two element is (2, 1) 2 + 1 = 3 < 9, Product of (2, 1) 2*1 = 2. Thus, output is 2
Sample Input
sum:4
size of Arr = 6
Arr:9 8 3 -7 3 9
Sample Output
-21
Question:4
(Asked in Accenture Offcampus 1 Aug 2021, Slot 1)
Implement the following functions.a
char*MoveHyphen(char str[],int n);
The function accepts a string “str” of length ‘n’, that contains alphabets and hyphens (-). Implement the function to move all hyphens(-) in the string to the front of the given string.
NOTE:- Return null if str is null.
Example :-
- Input:
- str.Move-Hyphens-to-Front
- Output:
- —MoveHyphenstoFront
Explanation:-
The string “Move-Hyphens -to-front” has 3 hyphens (-), which are moved to the front of the string, this output is “— MoveHyphen”
Sample Input
- Str: String-Compare
Sample Output-
- -StringCompare
Question:5
(Asked in Accenture Offcampus 1 Aug 2021, Slot 2)
Problem Statement
A carry is a digit that is transferred to left if sum of digits exceeds 9 while adding two numbers from right-to-left one digit at a time
You are required to implement the following function.
Int NumberOfCarries(int num1 , int num2);
The functions accepts two numbers ‘num1’ and ‘num2’ as its arguments. You are required to calculate and return the total number of carries generated while adding digits of two numbers ‘num1’ and ‘ num2’.
Assumption: num1, num2>=0
Example:
- Input
- Num 1: 451
- Num 2: 349
- Output
- 2
Explanation:
Adding ‘num 1’ and ‘num 2’ right-to-left results in 2 carries since ( 1+9) is 10. 1 is carried and (5+4=1) is 10, again 1 is carried. Hence 2 is returned.
Sample Input
Num 1: 23
Num 2: 563
Sample Output
0
Question:6
(Asked in Accenture Offcampus 2 Aug 2021, Slot 1)
Problem Statement
You are required to implement the following function.
Int OperationChoices(int c, int n, int a , int b )
The function accepts 3 positive integers ‘a’ , ‘b’ and ‘c ‘ as its arguments. Implement the function to return.
- ( a+ b ) , if c=1
- ( a – b ) , if c=2
- ( a * b ) , if c=3
- (a / b) , if c =4
Assumption : All operations will result in integer output.
Example:
- Input
- c :1
- a:12
- b:16
- Output:
- Since ‘c’=1 , (12+16) is performed which is equal to 28 , hence 28 is returned.
Sample Input
c : 2
a : 16
b : 20
Sample Output
-4
Question:7
(Asked in Accenture Offcampus 2 Aug 2021, Slot 2)
Problem Statement
You are given a function,
Int MaxExponents (int a , int b);
You have to find and return the number between ‘a’ and ‘b’ ( range inclusive on both ends) which has the maximum exponent of 2.
The algorithm to find the number with maximum exponent of 2 between the given range is
- Loop between ‘a’ and ‘b’. Let the looping variable be ‘i’.
- Find the exponent (power) of 2 for each ‘i’ and store the number with maximum exponent of 2 so faqrd in a variable , let say ‘max’. Set ‘max’ to ‘i’ only if ‘i’ has more exponent of 2 than ‘max’.
- Return ‘max’.
Assumption: a <b
Note: If two or more numbers in the range have the same exponents of 2 , return the small number.
Example
- Input:
- 7
- 12
- Output:
- 8
Explanation:
Exponents of 2 in:
7-0
8-3
9-0
10-1
11-0
12-2
Hence maximum exponent if two is of 8.
