Source Code:

function count_colors(str)

var words=str.split(" ");

var colors=["blue","green","brown","gray","black","brown","red","purple"];

var count=0;

for(var i=0;i<words.length;i++)

{

for(j=0;j<colors.length;j++)

{

if(words[i]==colors[j])

{

count=count+1;

break;

}

return count

}

var str="The quick brown fox jumped the blue fence and landed on red paint.";

Write a function that takes a C string as an input parameter and reverses the string.

in c++ Write a function that takes a C string as an input parameter and reverses the string. The function should use two pointers, front and rear. The front pointer should initially reference the first character in the string, and the rear pointer should initially reference the last character in the string.

Write a function in R named counts. This function should take as parameters a numeric vector x and also a number indicating a number of bins n. The function will consider the range [min(x),max(x)], and then consider a parti- tion of this interval into n non-overlapping equally sized half open intervals: I1 = [min(x),b1),I2 = [b1,b − 2),...,In = (bn−1,max(x)]. Note that since the intervals are equally sized, the value of bi is constrained. The function will then return a...
