- Write the reccurence relation for the following function (in C-style code) void T(n){ if(n>1){ int j; for(j = n; j>1; j = j/2); T(n/2); T(n/2); } }(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.Instructions: In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString(). This preserveString() function has the following description: Return type - void Name - preserveString Parameters The string Length of the string Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function. Please Finish the code ASAP: This is my current given code: #include<stdio.h>#include<string.h> #define STR_MAX_SIZE 100 void preserveString(char*, int); int main(void) { char str[STR_MAX_SIZE]; printf("Enter string: "); fgets(str, STR_MAX_SIZE, stdin); preserveString(str,…
- Exponent y Catherine Arellano mplement a recursive function that returns he exponent given the base and the result. for example, if the base is 2 and the result is 3, then the output should be 3 because the exponent needed for 2 to become 8 is 3 (i.e. 23 = 8) nstructions: 1. In the code editor, you are provided with a main() function that asks the user for two integer inputs: 1. The first integer is the base 2. The second integer is the result 2. Furthermore, you are provided with the getExponent() function. The details of this function are the following: 1. Return type - int 2. Name - getExponent 3. Parameters 1. int - base 2. int - result 4. Description - this recursive function returns the exponent 5.

For this problem, you are task to implement the computeReverseNumber function. This function will take in an integer n as its parameter. This will get the reverse of the passed integer and will then compute and return the value: result = (original_number + reverse_of_the_number) / 3 In the main() function, ask the user to input the value of n, call the function computeReverseNumber and pass the inputted value of n, and print the result in the main() with two (2) decimal places.

Infix expressions is the common way of writing arithmetic expressions. The binary operator come between them as shown below: 2 * 5 + 9 - 10 / 20 In postfix expressions, the operands come first before the operator: 2 5 * 9 + 10 20 / - A stack can be used to evaluate postfix expressions. The operands are pushed onto the Stack and when an operator is found two operands are popped and the operation is performed and finally the result is pushed back onto the Stack. The final answer will be the lone element of the Stack. Input The first line contains a positive integer n representing the number of postfix expressions. What follows are n postfix expressions themselves. 5 10 20 + 30 15 2 * + 100 20 30 + / 90 20 10 + + 0 / 9 3 - 10 + 2 * Output A single line containing the result of…SEE MORE QUESTIONS
