In java code:

Write a function int solution(int N, char CH)

that accepts integer N and characterCH. The function should return square ofa number (N) if a character (CH) is "s" otherwise return cubeof a number.

int solution(int N, int M, char CH)

that accepts two integers (N and M) and one character CH. Thefunction should return the product of two integers if a character(CH) is ‘p’ otherwise return their sum.

boolean solution(String S1, String S2) that accepts two stringsS1 and S2. The function should return true if S1 and S2 are equalotherwise false.

Input
1
4
s

where,

• First line represents a choice for calling one of the definedmethods. (1 for solution(int N, char CH), 2for solution(int N, int M, char CH) and 3for solution(String S1, String S2)).
• Second line represents number input.
• Third line represents choice CH.

Output
16

Here, the first line contains 1 and hence solution(int N,char CH) will get invoked. And since the number is 4 and choice CHis ‘s’, the function returns 16.
