Lab03-07. Searching for a target can be faster if the elements in the file are sorted (are in order). Use a text editor to create a file of integers separated by one space character as shown below. Then use a program to find if a given integer is in the file. Note that searching time makes a lot of difference if the file is very large, although we test with a small file. 14 17 24 32 48 52 64 74 81 92

Write a program that uses the natural merge algorithm on the two data files provided (merge_1.txt and merge_2.txt) to merge the two files into one, and then state which value appears at index 100. File format: a single integer that is the number of values to follow, followed by at least that number of integers. That first integer is not part of the data. merge_1.txt 100350 659 684 484 735 514 723 473 127 747 735 167 482 954 914 173 186 910 819 879 403 543 776 674 796 342 84 197 130 968 296 863 739 6 301 684 542 515 199 310 338 274 3 57 391 411 968 621 901 370 16 136 818 56 28 171 599 331 979 329 919 946 814 88 75 425 691 650 777 374 688 625 315 199 412 536 617 200 938 293 560 623 426 958 991 279 321 389 310 5 500 578 161 356 889 792 685 625 59 971 merge_2.txt
After every word on a line is spellchecked, it should be written to an output file called checked.txt. The arrangement of words on lines should be the same in the document and in checked.txt. The difference between the document and checked.txt is that in checked.txt each word is in lowercase and there is no punctuation. Also, some words might be changed by the spellcheck process. For example, suppose the document contains the following: The Hunter Moon waxed round in the night sky, and put to flight all the lesser stars. But low in the South one star shone red. Then checked.txt will contain: the hunter moon waxed round in the night sky and put to flight all the lesser stars but low in the south one star shone red (In a real spellchecker, the output will be in the same case as the original, and all punctuation will be retained. For simplicity, we will not worry about case and punctuation.) How to Process Words Which Are Not in the Dictionary The spellcheck method also needs to handle…
A computer runs a program to generate all the strings from a set of characters,then search a dictionary to see if each word generated is in the dictionary. Itthen writes the output to a file at a rate of 1200 words/sec all generated andchecked. How long will it take the computer to generate, check and output all thewords from a string of 5 (distinct) characters? How long if there are repeatedcharacters?
Computer Science For each of the code snippet given below, identify the error and then write code after fixing the error. Given code is the simulation of grep -v command. -v prints all lines that do not match a specific pattern. void grep_inverse(char *filename, char *str) { FILE *fp; char buf[buff_size]; fp = fopen(filename, "r"); if(!fp) { perror(filename); } else { while (fgets(buf, buff_size, fp) != NULL) { if ((strstr (buf, str)) != NULL) printf("%s", buf); } } fclose(fp); }
Write a program that will sequentially list numbers from 0 to 50, changing its color depending on the size of the number, for example, for numbers from 0 to 10 it will be green, 11 to 22 red and 23 to 35 blue, etc. Limit the screen output speed to about 1 character / second. In order to change colors, you must first use the GetStdHandle function to get a handle to the console, which is similar to getting a file pointer before working with a file. It is done e.g. as follows: HANDLE hConsole; hConsole = GetStdHandle (STD_OUTPUT_HANDLE); The above functions are defined in windows.h Tip 2: Write a utility to find out the colors corresponding to all combinations from 0 to 255. Tip 3: Instructions and sample program for working with time. C language plz with explanation of codes. thanks

write program code in java: Write a program that reads two files “Data1.txt”, “Data2.txt”; Then add their corresponding elements and produce an output file “output.txt”. If the number of elements are not equal, fill the elements of the smaller file up with “0” s. Sample output: Elements of the “Data1.txt”: 3 5 7 8 9 Elements of the “Data2.txt”: 45 11 Elements of the “Output.txt”: 48 16 7 8

you will be identifying which organisms are the tastiest. The tastiest organisms are the ones that appear the most times as a food source. For example if aquatic.txt was the input file, file_list will be: ["Bird,Prawn,Mussels,Crab,Limpets,Whelk\n", "Crab,Mussels,Limpets\n", "Fish,Prawn\n", "Limpets,Seaweed\n", "Lobster,Crab,Mussels,Limpets,Whelk\n", "Mussels,Phytoplankton,Zooplankton\n", "Prawn,Zooplankton\n", "Whelk,Limpets,Mussels\n", "Zooplankton,Phytoplankton"] Limpets and mussels appear the most times as a food source, making them the tastiest organisms. Here is a sample output using aquatic.txt: Enter the food web file name: aquatic.txt Predators and Prey: Bird eats Crab, Limpets, Mussels, Prawn, and Whelk Crab eats Limpets and Mussels Fish eats Prawn Limpets eats Seaweed Lobster eats Crab, Limpets, Mussels, and Whelk Mussels eats Phytoplankton and Zooplankton Prawn eats Zooplankton Whelk eats Limpets and Mussels Zooplankton eats Phytoplankton Apex Predators:…
Write a program that can read in a rank 2 array from an input disk file and calculate the sums ofall the data in each row and each column in the array. The size of the array to read in will bespecified by two numbers on the first line in the input file, and the elements in each row of thearray will be found on a single line of the input file. Use allocatable arrays that are adjusted tomatch the number of rows and columns in the file each time the program is run. An example ofan input data file containing a 2 row × 4 column array is shown below:
