- (C Language) The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.Describe each of the following sets by listing its elements:a. {x | x ∈ N and x2 − 5x + 6 = 0}b. {x | x ∈ R and x2 = 19}c. {x | x ∈ N and x2 − 2x − 8 = 0}}d. {x | x ∈ Z and x ∗ x = 4}6.Code for an array of meeting time intervals consisting ofstart and end times [[s1,e1],[s2,e2],...] (si < ei),determine if a person could attend all meetings. For example,Given [[0, 30],[5, 10],[15, 20]],return false.""".
- Transcribed Image Text DNA is sequence of bases A, G, T, C. Let DNA [ab] be the subsequence of DNA starting from index a finishing in b inclusive, and DNA[a.] be the subsequence of DNA starting from index a to the end. We could perform the following ops on DNAS: cross operation - they take DNA1 and DNA2 and numbers kl and k2. Then two new DNAS are created: DNA3 = DNA1[1,,k1]+DNA2[k2+1.] and DNA4 = DNA2[1.k2]+DNA1[k1+1.].mutate operation - they take a DNA, number k and one of the bases. Then they replace the base in position k in DNA with that base. also, they need to know certain characteristics of those DNAS. So, they can perform count operation - they take DNA and numbers k1 and k2 (k1 <= k2). This operation should return the number of A, G, T, C bases in DNA[k1,,k2].The initial DNAS are numbered from 1 to n, where n is the amount of those DNAS. The new DNAS the first line of input file contains number n - the number of initial DNAS. Each of the following n lines containsextern "C" int f(int *,int,int); int a[2][2] = {{11,12},{21,22}}; void setup(){ Serial.begin(115200); while(!Serial); delay(500); int *arr = (int*)a; Serial.println(f(arr,2,2)); } void loop(){ } .global f f: ldr r3,[r0] // get first element mov r2,#0add r2,r3 mov r1, #3 lp: add r0,#4 // add next elementldr r3,[r0]add r2,r3sub r1,#1 bgt lp mov r0,r2 bx lr Describe what operation is being performed in this codeQuestion 15 ka R Programming - 1) Without using the dplyr package explain the various ways of subsetting rows and columns in a data frame in base R. 2) Write a for loop with: - if else conditions in it. - assign function - which makes use of empty vector or empty lists Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this line
- 8.26 LAB: Word frequencies (dictionaries) Implement the build_dictionary() function to build a word frequency dictionary from a list of words. Ex: If the words list is: ["hey", "hi", "Mark", "hi", "mark"] the dictionary returned from calling build_dictionary(words) is: {'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1} Ex: If the words list is: ["zyBooks", "now", "zyBooks", "later", "zyBooks", "forever"] the dictionary returned from calling build_dictionary(words) is: {'zyBooks': 3, 'now': 1, 'later': 1, 'forever': 1} The main code builds the word list from an input string, calls build_dictionary() to build the dictionary, and displays the dictionary sorted by key value. Ex: If the input is: hey hi Mark hi mark the output is: Mark: 1 hey: 1 hi: 2 mark: 1 Use Python, please.def find_root4(x, epsilon): ''' IN PYTHON Assume: x, epsilon are floating point numbers and epsilon > 0 Use bisection search to find the following root of x such that If x >=0, return y such that x - epsilon <= y ** 2 <= x + epsilon Else, return y such that x - epsilon <= y ** 7 <= x + epsilon Note: You must use bisection search to implement the function.
