Turn Off Bit
The function accepts a positive integer array ‘n’ and position of the bit to be turned off ‘k’. Implement the function to turn off the kth bit of the binary representation of ‘n’ and return decimal equivalent of the obtained number. Consider position of ‘k’ according to “little Endian’ notation (i.e. right to left).
Assumptions:
k>0
The number of bits of the binary representation of ‘n’ is >=k
Note:
When counting the bits from right to left, start counting from 1.
Return ‘n’, if kth bit is already off.
Example:
Input:
n: 19
k: 2
Output: 17
Explanation:
n : 19
Binary Representation of n : 10011
k : 2
Binary Representation of number after turning off kth bit : 10001
return Value : 17
Sample Input:
n : 13
k : 3
Sample Output :
9
