Security System

You are working on a security system that uses a binary key to unlock a vault. The key consists of a series of bits, each representing a specific function of the security system.

You are given an integer value N$,$ which represents the curfent binary key configuration gor and an integer value B$,$ which represents the bit position that needs to be toggled to

activate the security feature.

a Your task is to find and return an integer value representing the updated binary key configuration after toggling the Nth bit to activate the security feature.

Note: Toggling a bit means changing it from $0$ to $1$ or from $1$ to $0.$

Input Specification:

input$1$: An integer value N$,$ representing the current binary key configuration input$2$: An integer value B$,$ representing the bit position to toggle for activating the security feature

Output Specification:

Return an integer value representing the updated binary key configuration after toggling the Nih bit to activate the security feature.

Example $1$:

input$1$: $37$

input$2$: $3$

Output : $45$

Explanation:

Here, N $=37$ and B $=3.$ The binary representation of $37$ is $100101.$ Toggling the $3$rd bit

results in $101101,$ which is equivalent to $45$ in decimA notation. Hence, $45$ is returned as the output.

Example $2$: input$1$: $15$

input$2$: $2$

Output : $11$

Explanation:

Here, N $=15$ and B $=2.$ The binary representation of $15$ is $1111.$ Toggling the $2$nd bit

results in $1011,$ which is equivalent to $11$ in decimal notation. Hence, $11$ is returned as the output.
