Problem statement

\n

Write a function that takes in a positive number N and console logs a staircase pattern using the # character. The number of steps in the staircase should be equal to N.

\n

Also, ensure that the step has spaces on the right hand side. The following examples should make the problem statement clear.

\n

Example:

\n
steps(2)\n//    '# '\n//    '##'\n\nsteps(3)\n//    '#  '\n//    '## '\n//    '###'\n\nsteps(4)\n//    '#   '\n//    '##  '\n//    '### '\n//    '####'
\n

Solution

\n

To solve the staircase problem, we will use nested for loops: one for loop inside of another.

\n
const steps = n => {\n  for (let row = 0; row < n; row++) {\n    let stairs = ""\n\n    for (let column = 0; column < n; column++) {\n      if (column <= row) {\n        stairs += "#"\n      } else {\n        stairs += " "\n      }\n    }\n\n    console.log(stairs)\n  }\n}\n\nsteps(4)\n// #\n// ##\n// ###\n// ####
