When it is required to replace all the occurrences of ‘a’ with a character such as ‘$’ in a string, the string can be iterated over and can be replaced using the ‘+=’ operator.Below is a demonstration of the same −Example Live Demomy_str = "Jane Will Rob Harry Fanch Dave Nancy" ... Read More

When it is required to find an element that occurs odd number of times in a list, a method can be defined. This method iterates through the list and checks to see if the elements in the nested loops match. If they do, the counter is incremented. If that count ... Read More

When it is required to remove a specific occurrence of a given word in a list of words, given that the words can be repeated, a method can be defined, that iterates through the list, and increments the counter by 1. If the count and the specific occurrence match, then ... Read More

ProblemWe are required to write a JavaScript function that takes in an array of integers as the first and the only argument. Our function should return true if and only if we can partition the array into three non-empty parts with equal sums, false otherwise.For example, if the input to ... Read More

ProblemWe are required to write a JavaScript function that takes in a binary arr (array that contains only 0 or 1), arr, as the first argument, and a number, num, as the second argument.We can change at most num 0s present in the array to 1s, and our function should ... Read More

ProblemWe are required to write a JavaScript function that takes in an array of literals, arr, as the first argument. The second argument to our function will be a number, num. Our function should count and return the number of subarrays of the array that contains exactly num distinct elements.For ... Read More

ProblemWe are required to write a JavaScript function that takes in two numbers, m and n, as the first and the second argument.Our function is supposed to count the number of minimum operations required to reach n from m, using only these two operations −Double − Multiply the number on ... Read More
